Health and safety publications and forms published by the HSA. Since all these applications require different installation procedures, this section will focus on OSP installation in more detail. The Installation. After the process of designing fiber optic networks is completed, the next step is to install it. What do we mean by the “installation process?” Assuming the design is completed, we’re looking at the process of physically installing and completing the network, turning the design into an operating system. This chapter covers preparing for the installation, requirements for training and safety and then the actual installation process. Since outside plant fiber optic networks can cover a broad range of installation types using varied components over different types of geography, it is impossible to cover the specifics of any one installation. This chapter should provide an overview of the various options available in OSP installations and general knowledge that should prepare those involved in any particular installation to understand how to proceed. The Role of the Contractor in an Installation. 2 day CCTV training course aimed at operators or people involved in CCTV Inspections of sewer and stormwater systems.To begin work on a fiber optic installation, the network owner or user must choose a contractor, perhaps the most important decision in the entire process. The fiber optic contractor should be able to work with the customer in each installation project through six stages: design, installation, testing, troubleshooting, documentation and restoration. The contractor must be experienced in fiber optic installations of the type involved and should be able to provide references for similar work. One should be able to rely the contractor to not only do the installation but to assist in the design of the network and help choose components and vendors. The Problem of School Vandalism and Break-Ins. This guide addresses school vandalism and break-ins, describing the problem and reviewing the risk factors. Introduction. In this paper, we address the question: how susceptible are jobs to computerisation? Doing so, we build on the existing literature in two ways. Once the contractor has been given the assignment, they should be able to help the customer with the design, including choosing the right kinds of fibers, cables, connectors and hardware for the installation. The contractor should know which components meet industry standards to ensure interoperability and what state of the art components will facilitate future expandability. The experienced contractor also should be able to help in the choice of vendors. Experience with particular product types and vendors will allow the contractor to assist the customer to choose products that make the installation faster and easier and often higher performance and more reliable. Should the customer choose components that are unfamiliar to the contractor, it is important that the contractor know early in the process so they may obtain proper training, often from the manufacturer, as well as any unique tools that may be required. Generally, the customer is not as familiar with fiber optic technology and practice as an experienced contractor. The contractor may need to discuss certain choices with the customer where they believe alternatives may be better choices. The actual installation process can involve more than just putting in cable, terminating and testing it. If the contractor is knowledgeable and experienced, the user may ask the contractor to purchase, receive, inspect and bring components to the work site also, which can be another good source of revenue for the contractor. Having full control of the materials process can also make life easier for the contractor, as they have a better chance to keep on schedule rather than depending on a customer who has many other priorities. Plus, they may have the latitude to choose components they are more familiar with, facilitating the actual installation process. The mission of The Center for Problem-Oriented Policing is to advance the concept and practice of problem-oriented policing in open and democratic societies.
The technicians actually doing the installation should be trained and certified by organizations like The Fiber Optic Association (www. Certification provides a level of confidence that the installation techs are knowledgeable and have the skills needed for the work involved. The final four requirements from the contractor, testing, troubleshooting, documentation and restoration, need to be discussed before the project ever begins. Every fiber optic project requires insertion loss testing of every link with a light source and power meter or optical loss test set according to industry standards. Some projects, like long outside plant links with splices, may also require OTDR testing. The contractor and customer must agree that testing includes troubleshooting problems and fixing them as well as documenting test results for every link. Likewise, for the contractor, documentation must begin before the project starts so the scope of work is known to everyone and end only when the final test data is entered. Copies of the documentation, along with excess components left over from the installation, must be presented to the customer to facilitate future network restoration, should it be required. The Contract. The contract for a fiber optic installation should include detailed requirements for the project, spelling out exactly what is to be installed, acceptable test results, and documentation to be provided. All this should be discussed between the customer and the contractor and agreed to in writing. They are not irrelevant details, as they are important to ensure the customer gets what they expect and the contractor knows what is expected of them when designing the network, estimating costs, doing the actual installation and providing proof of performance in order to show the work is completed and payment should be made. Planning For The Project. Once the contracts are signed and a set of plans has been handed to the contractor, what’s next? Planning the job is the first task. Proper planning is important to ensure the job is installed properly, on time and meets cost objectives, so the contractor can make a profit. It is assumed you have a finished design for the project, know where and how everything will be installed and have any special requirements like permits ready. One can also assume you have a completion date, hopefully a reasonable one, to work toward. The first step then is to create a schedule which will be the centerpiece of the planning process. In order to schedule a job, you need a lot of information, much of which can be acquired from estimates you did when bidding the job. When buyers price the components to be used on a job, they should get delivery times as well as prices. Some items used on fiber optic projects should be stock items, like connectors, patch panels or splice closures. Cables, however, may have to be made to order. Many fiber optic cables are custom items, depending on the cable type, number and types of fibers and color coding. Custom cables will often be less expensive because they don’t have extra fibers for specifications you don’t need, for example, but they will have longer lead times since they must be made from scratch. Whenever specifying a fiber optic cable, always try to have a few extra fibers available, just in case fibers are damaged during installation. The astute contractor tries to always use the same types of components on every job so they are familiar with not only the installation procedures but the typical costs, yield (i. If any components are not familiar to the installers, they need to learn how to install them correctly, either by experimenting in the office on off- time or getting manufacturers to train them. The need for training may also arise if new equipment types are required, such as outside plant cable placing tools or new types of test equipment. The cardinal rule of installation is never take an unfamiliar component or tool on the job; it’s a recipe for disaster. Buyers need to order the components when the job is acquired, scheduling delivery to the job site either to have everything available before the installation begins, or on a large job with an extended schedule, according to how long the installation of that component will take. Here you also need to plan on where the components will be delivered to, either a staging area in your warehouse, for example, or to the job site. Components delivered to the job site may require security. Theft can be a problem with cable particularly, since many thieves think all cables contain copper and the price of copper makes cable worth stealing. But vandalism is another concern, requiring components be either locked up or if too large to put indoors like large spools of cable or fiber optic innerduct, may require on site overnight guards. Next, one needs to schedule labor. Again, the estimates should tell you how many installers of what experience will be needed and how long they are expected to need to complete the installation. If any training is needed, additional time may need to be added to the schedule. Having covered labor and materials in the schedule, the planning is almost done. Review the schedule with everyone involved to get them on board and start the processes, beginning with acquiring materials. Then add to the plan a review of safety rules for supervisors, installers and anyone expected to be on site. Also add notes to keep all scrap cable, connectors, etc. The best way to keep everything straight is to develop a checklist based on the design. The checklist below is comprehensive but each project will have some of its own unique requirements that need to be added to the list. Pre- install checklist: Main point of contact/project manager chosen.

The Bling- Bling Generation: How Spinners Work. If you're a car aficionado, we're pretty sure you have already heard of spinners, or spinning rims, or however you like to call those flashy rims that keep spinning even after the vehicle comes to a halt. Usually installed on large SUVs or massively tuned cars, spinners are nothing more than eye- catching accessories supposed to add a touch of style to any ride out there. Well, spinners have been around for a while and there are voices claiming that they're quickly losing popularity no matter what. With an immense success among hip- hop fans, the spinning rims are originally from the United States and it's no surprise why. We've seen them in tens of hip- hop music videos, often on Cadillacs and alongside low- riders, and their only goal was to prove the world that rappers know how to ride in style. Or not. Now, since they're coming from the United States, you're probably wondering how this whole spinners frenzy started.. Well, it seems like the first time the term wheel spinner was brought in discussion was on October 2. James D. Gragg from Tulsa, Oklahoma filled a patent for what he called “a wheel enhancing apparatus comprising a center cap and a wheel mounting assembly for mounting the center cap on the center cone of a wheel such that the center cap will rotate independently of the wheel”. Additionally, the inventive apparatus provides a means for rotatably mounting an object on a vehicle wheel in a secure and safe manner. Further, the inventive apparatus provides a highly theft- resistant means for rotatably mounting an object on a vehicle wheel,” the patent reads. With a pretty simple definition, the first spinners reached the market in mid- 1. Since their popularity was skyrocketing in early 2. Three 6 Mafia through their so- called “Ridin' Spinners” single, which you can watch below. Afterwards, many rappers and basketball players adopted spinners in their clips, just because they look good. Among them, Busta Rhymes and Shaquille O'Neal. As you can see, you don't need to learn rocket science to design a spinning rim, and the whole technology, if it could be really named so, comes down to just a few components. Before getting too technical, here's the general idea: every spinner makes use of the principle of inertia and relies on ball bearings. Centrifugal force is the secret that makes the rims keep spinning once the car comes to a halt, so everything's pretty simple. Still, not all rims can use spinners. A specially- designed rim comes, as we said, with a bearing system that's being used to hold the spinner. Once the car starts moving, the bearing system we were talking about starts moving, while the original spinner does the same thing, in the same direction, but slower, especially due to the centrifugal force and the friction. Hence the spinning effect that so many people find very stylish. Since spinners are only supposed to make a wheel look good and nothing more, there are numerous types and models out there, and a simple search on Google reveals that pricing starts at around $5. Some of them simply attach to the original wheel and sometimes stick out and look just.. And the general idea is more like this: “Oh, forget it, if those rappers want to look stupid, let them use the silly spinners”. Only that spinners do a bit more than that. There are reports from all over the world that spinners are also affecting the other drivers on the road and although this may sound a bit uncanny, there's some truth behind those complaints. Spinners are flashy, right? They spin even if a car is not in motion, don't they? Well, all things being considered, a spinner makes a car look like it's moving, a fact that may bother some of the other drivers and make them push the brake pedal as hard as they can. And it's pretty obvious that accidents can occur fairly easy if such a scenario takes place. Of course, there's no law against spinners and people can use them freely on any type of road they want. Those being said, besides a striking exterior color, spinners are the easiest way to make yourself noticed even when not in motion. Truth is, bystanders may believe that you're either a pimp or a rapper. And we're not so sure that these are exactly your intentions. SQL Insert, Select, Update, and Delete Examples.

DB by the user root and password secret: String db. URL = . In the above code, we have to close the connection explicitly after finish working with the database: conn. However, since Java 7, we can take advantage of the try- with- resources statement which will close the connection automatically, as shown in the following code snippet: try (Connection conn = Driver. Manager. get. Connection(db. URL, username, password)) . The sample programs in this tutorial are all using this try- with- resources statement to make a database connection.

Executing INSERT statement Let’s write code to insert a new record into the table Users with following details: username: billpassword: secretpassfullname: Bill Gatesemail: bill. Here’s the code snippet: String sql = . To set values for the parameters in the INSERT statement, we use the Prepared. Statement. Note that the parameter index is 1- based (unlike 0- based index in Java array). The Prepared. Statement interface provides various set. XXX() methods corresponding to each data type, for example: set. Boolean(int parameter. Index, boolean x)set. Date(int parameter. Index, Date x)set. Float(int parameter. Index, float x). Which method to be used is depending on the type of the corresponding column in the database table. Finally we call the Prepared. Statement’s execute. Update() method to execute the INSERT statement. This method returns an update count indicating how many rows in the table were affected by the query, so checking this return value is necessary to ensure the query was executed successfully. In this case, execute. Update() method should return 1 to indicate one record was inserted. Executing SELECT statement The following code snippet queries all records from the Users table and print out details for each record: String sql = . The while loop iterates over the rows contained in the result set by repeatedly checking return value of the Result. Set’s next() method. The next() method moves a cursor forward in the result set to check if there is any remaining record. For each iteration, the result set contains data for the current row, and we use the Result. Set’s get. XXX(column index/column name) method to retrieve value of a specific column in the current row, for example this statement: String name = result. String(2). Retrieves value of the second column in the current row, which is the username field. The value is casted to a String because we know that the username field is of type VARCHAR based on the database schema mentioned previously. Keep in mind that the column index here is 1- based, the first column will be at index 1, the second at index 2, and so on. If you are not sure or don’t know exactly the index of column, so passing a column name would be useful: String fullname = result. String(. Executing UPDATE statement The following code snippet will update the record of “Bill Gates” as we inserted previously: String sql = ? WHERE username=? Executing DELETE statement The following code snippet will delete a record whose username field contains “bill”: String sql = . The key points to remember are: Using a Statement for a static SQL query. Using a Prepared. Statement for a parameterized SQL query and using set. XXX() methods to set values for the parameters. Using execute() method to execute general query. Using execute. Update() method to execute INSERT, UPDATE or DELETE query. Using execute. Query() method to execute SELECT query. Using a Result. Set to iterate over rows returned from a SELECT query, using its next() method to advance to next row in the result set, and using get. XXX() methods to retrieve values of columns. You can download source code of sample demo programs for each type of query in the attachments section. Quick Tip: Click Table Row to Trigger a Checkbox Click. Somebody on the j. Query Google Group asked the other day about toggling a checkbox within a table row when the user clicked anywhere within the row. This can be a nice feature to have, and it's also very straightforward to implement. The Basics. The one tricky part is that we don't want to trigger the click if the user clicks on the checkbox itself, because then it would effectively be clicked twice, once by the user and once programmatically. To avoid this, we can use the event argument inside the click handler. Let's take a look at how the code might be written: Java. Script: $(document). This way, the user will have one more visual indicator that the checkbox has been checked. We'll use the . toggle. Class() method so that it adds the class if it isn't there, and removes it if it is: Notice that the . Class() line is outside of the if statement. We want the class to toggle whether the actual target of the click is on the checkbox or not. If you look carefully at this table, you'll notice that the second row has a little problem. Since its checkbox is initially checked, the first click on that row adds the . Then we carry on with binding the click handler to the rows. This example should work as expected: These rows are also enhanced by a little CSS rule: . This gives the entire row the same cursor as the checkbox. The rule is applied only if Java. Script is enabled (see my previous post for details). Update. As of j. Query 1. Class() part of this code doesn't appear to work. In fact, it is being fired twice on each click. The problem has arisen because event bubbling is now supported for the . As the documentation states, . For example if you trigger an event on a ? I have two solutions, and I welcome others. Bind to the Checkbox. The first solution involves binding a click handler directly to the checkboxes for the . Class(). In this way, we take advantage of the triggered event bubbling. This fixes the problem, but I'm not crazy about it. It doubles the number of elements that have events bound to them, and I've been trying lately to reduce bound elements. Change the checked Attribute The second solution forgoes the click trigger in favor of simply changing the value of the checkbox's checked attribute. Java. Script: $(document). Again, if you have a better idea, please let me know (by posting it in the comments). With the updates, this hardly qualifies as a quick tip anymore. Oh well—back to our regularly scheduled blog post. If we try to achieve this effect with links, though, we'll have to do it a little differently. Here is a quick example: Java. Script: $(document).
