Activity Diagrams – Advantages, Disadvantages and Applications of Use

admin  Business  , , ,

Activity diagrams describe the actual work flow behavior of a system in Information Technology. Activity diagrams are very similar to state Diagrams because activities are the actual state of doing something. Activity diagrams describe the actual state of activities of a system by showing all the sequence of activities performed. Activity diagrams can show activities that are conditional or parallel.
When to Use: Activity Diagrams
Activity diagrams should be used in alignment with other modeling techniques like interaction diagrams and State diagrams. The main reason behind using activity diagrams is to model the work flow behind the system being designed. Activity Diagrams are also useful for analyzing a use case by describing what actions need to take place and when they should occur, describing a complicated sequential algorithm and modeling applications with parallel processes.

Activity diagrams’ advantages:
UML modeling language included that activity diagrams are normally easily comprehensible for both analysts and stakeholders.
According to ZaranTech in UML for the IT Business Analyst, “The activity diagram is the one most useful to the IT BA for depicting work flow [because] it is simple to understandboth for BAs and end-users.”
Since they are among the most user-friendly diagrams available, they are generally regarded as an essential tool in an analyst’s repertoire.
Additionally, as stated above, activity diagrams allow an analyst to display multiple conditions and actors within a work flow through the use of swimlanes. Swimlanes, however, are optional as a single condition or actor is normally displayed without them. Activity diagrams disadvantages:
UML modeling language include that activity diagrams have the potential to become overly complex because their user-friendly nature may lend itself to an all-inclusive description. In other words, since it is so simple to display the information related to the project, why not include all of it? When an analyst has a large project, creating a single, overly complex diagram can be a temptation.
However, as one author notes, “if you are using activity diagrams to define the structure of a work flow, you should not attempt to explore several levels of activity graphs down to their most atomic’ level”. Instead, an analyst should try to present a new diagram for each work flow, or if more applicable, to use swimlanes to present different actors within the same work flow.
Another aspect of activity diagrams is that they may not be used in lieu of a state diagram or sequence diagram because “activity diagrams do not give detail about how objects behave or how objects collaborate.” This is not a disadvantage per se, but it is important for an analyst to keep in mind when applying diagrams to their work. In conclusion, activity diagrams are fairly easy to get the hang of, and will be useful for most projects because they plainly and moderately clearly demonstrate how things work.” Unlike many diagramming techniques, activity diagrams also enable the depiction of multiple choices and actors within a work flow, and they are easy for even non-technical users to follow
Applications of activity diagram:
The activity diagram has been extended to specify flows among steps that transmit physical matter (e.g., gasoline) or energy (e.g., torque, pressure).
Additional changes allow the diagram to better support continuous behaviors and continuous data flows.
The UML 2 specification significantly prolonged the features and scale of activity diagrams beyond their earlier classification as a special case of state diagrams.
Today, activity diagrams can be thought of as flow charts for the 21st century, and UML modelers use activity diagrams to describe it.
Also, these activity diagrams are useful in following methods:
Business Rules
Functions that occur in parallel
Complex chain of multiple use cases
Software flows and logic control configurations
Procedures with judgment points and alternate flows
Single use cases

Construction Estimating Tips

admin  Construction

The first and foremost stage is drawing the plan for construction. Once the plan has been drawn the next stage is the stage of the construction estimate. The right estimation of cost is very important for going ahead appropriately with the plans of construction. The estimate should be accurate and should be such that considers all areas of cost. Cost estimation is not a simple task but is one that must be done systematically and accurately.

For drawing the correct estimate you must firstly gather the right information. The current cost of material, labor and other expenses must be gathered. The calculations must be made on the current costs so as to get a realistic picture. The estimate must take into account all heads of costs that would be incurred on the project and must also cater for the profit element.

The estimation of construction costs is actually a cumbersome time consuming activity, but is very important. No project can go ahead without an accurate construction estimate. The estimate regarding the overall project must be made along with the individual aspects. What you are constructing whether a house, office or anything else would make a big difference. The type of construction and what you are constructing would make all the difference to the requirements for the project. The difference in material and labor would bring about a difference in the cost of the project.

With the developments in technology working out the costs of construction has also been made simple. The specialized software for estimation of construction costs would be of great help in trying to find out the overall estimate of the project as well as finding the breakdown regarding the individual stages and areas. You could either use a specialized software meant only for the purpose or else there are templates that can be downloaded to equip your excel program to make some of the required calculations. The software meant for estimating construction costs can be used for finding out the details of cost estimation for individual portions of the entire project. Several options are available for you to choose from. The software is designed to handle multiple functions and greatly simplifies the task of cost estimation. There are also features that help merge details of one project with that of another. It makes cost estimation simple as well as quick. The changes made can also be calculated in no time at all. The construction cost estimating software is a simple and quick way of making accurate cost estimates.

Top 12 Automotive Wiring Tips

admin  Automotive  , , ,

The best connection is a properly done solder joint. If you aren’t sure how to solder, crimp the connection then solder it. Cold solder joints not only introduce resistance, but they can come apart.

2) Keep your grounds as short as possible. It is far better to have a few more connections than a long ground that can build heat and introduce ground loops. It is common practice to run a ground wire from a high demand devise such as a fuel pump back to the battery. This not only adds additional loads to the pump or devise but also can lead to device failure. Have you ever seen a production auto with a ground cable longer than the positive cable?

3) If at all possible, use stainless hardware to fasten all primary cables. Some galvanic or plated hardware can cause dissimilar corrosion and can sometimes carry more impedance that its stainless counter parts. On smaller secondary circuits, this is not as important.

4) Battery storage. Keep batteries away from humidity. Keeping it charged will prolong its life. If a battery is dead, cool it before you charge it. Put in the refrigerator or outside if its cold. Cool batteries charge better.

5) Batteries specifications and charge rates are for 77 degrees Fahrenheit. Temperature variations will change charge rates.

6) Use relays. Anytime you want to switch a device that draws more current than is provided by an output of a switch or component you’ll need to use a relay. The coil of an SPDT relay that we most commonly use draws very little current (less than 200 milliamps) and the amount of current that you can pass through a relay’s common, normally closed, and normally open contacts will handle up to 30 or 40 amps. This allows you to switch devices such as headlights, parking lights, horns, etc., with low amperage outputs such as those found on keyless entry and alarm systems, and other components. In some cases you may need to switch multiple things at the same time using one output. A single output connected to multiple relays will allow you to open continuity and/or close continuity simultaneously on multiple wires.

7) Most electromechanical devises are rated according to the MTBF (Mean Time Between Failures). You improve your odds of a long MTBF by keeping your electrical devices in a low humidity, low heat environment.

8) Do not ever use THHN/THWN wire. This wire (insulation) classification is not rated for automotive use. Cars move and vibrate which chafes the insulating material.

9) A wire that is rated for A/C voltage may have a different rating when used in low voltage D/C applications. Your house uses A/C, your car uses D/C.

10) The best primary power cable is a type TEW or MTW (Machine Tool Wire) as its rated for continuous use with higher amperage loads.

11) OFC (oxygen free copper) is by far the best cable for automotive use. However, it is expensive and requires a quality crimper and should be soldered for security. The most common application for this wire is high-end car stereo applications.

12) If you are like me, you may choose to skip OFC and go with TXL wire. TXL (thermal cross-linked) wire is next best. TXL wire has twice the voltage rating of standard GPT (general purpose) wire. Most high-end harnesses are made with this wire. If you want to keep your ride for the long haul, you may want to pony up for a harness made with this wire.

Kitchen Cabinets Dovetailed Drawer Construction

admin  Construction  , ,

Dovetail joints is a common technique used in woodworking with some of the earliest known samples dating back to ancient Egypt. Today, this joinery method is widely used as one of the solutions to a durable construction of kitchen cabinets. If you shop around for cabinetry locally or via the Internet, you will notice this feature in most offered products. And this article discusses the essentials about dovetailed drawer construction and why this is an important factor to look into when buying your own collection of cabinet units.

Dovetailed Drawer Construction is mainly created by the wedge shaped cut channels known as tails and pins. The interlocking of these trapezoidal parts is the key to strength of the drawers as well as adds an interesting pattern and makes the pieces more attractive. These are then glued together for added security but even if they left unglued, these parts remain immovable. The strong joint makes your kitchen cabinets more resistant to force and damages. Other than drawers, this is also a joint style popularly used in making frames, furniture, and storage boxes.

Dovetailed drawer construction showcases the craftsmanship of cabinet makers. This pattern can be seen in many antiques. The interlocking sides are tapered and can be put together in only one direction. Meaning, if you slide it in, there is not other way to disassemble the pieces than by sliding it out again. This is among the most recognizable features indicating high-end craftsmanship and quality in wood furniture and cabinetry.

Aside from the durability and decorative benefits of dovetailed drawer construction, you can now create these woodworking joints easier with advanced tools. But even with modern equipment, carving these out in fine details will still require a fair amount of patience, skill, and craft. It is crucial that the joints are marked and cut accurately. Today, homeowners do not have to go through all the ordeal of woodworking as the advancements in technology has allowed manufacturing facilities to achieve perfect dovetails for kitchen cabinets.

With dovetailed drawer construction, the angle of slopes varies depending on the type of wood used. Generally, a slope of 1:6 is used for softwoods while a shallower slope of 1:8 is applied for hardwood kitchen cabinets. There are various types under this joint woodworking technique.

* Through or plain dovetails are commonly used in creating boxes and are traditionally covered by veneer.
* Half blind dovetails have tails housed in sockets situated at the end of boards and are usually used for attaching drawer fronts.
* Full-blind dovetails are implemented in fine wood work where strength is required without the obvious sight of interlocking pins and tails. This is also called “French Dovetail” and is commonly used in boxes and fine cabinetry.
* Sliding dovetails are by far the most popular with a range of many uses. The method involves two boards at right angles and is assembled by sliding tails into the sockets. Commonly used for: shelves to cabinet side joints, cabinet bottom to side joints, joining horizontal shelf partitions, drawer front to side joints, as well as joining front rails of frames to cabinet sides.

Risk Transfer With Construction Bond

admin  Construction  , , ,

Construction projects can often cause a tremendous amount of worry to the project owner. If you are the project owner there is a simple way to prevent the stress and worries caused by hiring a contractor to complete your project. Project owners can make certain that the contractor they hire will perform as expected if they are bonded.

Construction Bonds protect both the project owner as well as the contractor. Contractors can easily obtain a bond within a week so there is no reason one should not obtain a bond. Even if the contractor is inexperienced he is still capable of obtaining a bond.

Contractors who are bonded have a greater advantage over other contractors for many reasons.
Bonds prove to a project owner that the contractor is financially strong, competent and well capable of completing the project without complications. Having a bond will protect the project owner by a process called risk transfer. This means that the insurance company guarantees that the work of the contractor will be provided within the project owners stated budget and time frame requirements through a written contract.

The size of a project is no issue as a construction bond will cover a contractor for any size project whether it is a small project or a very large, time consuming project.

Construction Bonds may include up to five different types of bonds covering any issues that may arise from the starting of a project all the way to the completion of the project and any people involved during the process.

Tender or Bid Bonds are in place to show the project owner that there is a guarantee. This bond is a very important to the contractor since it shows to project owners that the contractor will honor their bid. Contractors who have bid bonds show that they are worthy of hiring because having a bid bond proves that the contractor will provide a Performance Bond if their bid is successful.

Performance Bonds reassure project owners that if the contractor were to default, the owner will not be at a loss. Performance Bonds make a set value of funds available to complete the contract in this event.

Maintenance Bonds also provide a guarantee to the project Owner in a similar way. This type of bonds reassures that the contractor will abide by their obligations of the contract they have signed including any maintenance or defective work obligations.

Stage Payment Bonds, also known as Advancement Bonds/ Advance Bonds, are one of the most beneficial bonds for the contractor as they provide the contractor with a direct service. Advance Bonds allow the contractor advancements in funds to allow him to purchase the initial necessary supplies and materials in order to start on his work without taking a personal loss in cash flow.

Payment Bonds are another important guarantee however they arent necessarily beneficial for either the contractor or the project owner. Payment Bonds are formed to provide security for the subcontractors or other laborers and those supplying the materials under the actual contractor. Having this bond in place guarantees a payment amount to these people which is a protection to them since no other bonds offer protection to these workers.
