Abstract:The Department of Transportation (DISHUB) of Tegal Regency as the organizer of the highway has difficulties in monitoring road equipment due to the small number of personnel with a fairly large work area. Complaints by the public regarding maintenance of road equipment such as lacking or damaged road equipment are needed by DISHUB as input to be more effective and quick in collecting road equipment data. The main objective of this research is to create alternative solutions that can help DISHUB in maintaining road equipment. Data collection techniques by observation, interview, and literature study. The Extreme Programming method is used as a software development method. The results of this research are the Geographical Information System of the Highway that can be utilized by DISHUB of Tegal Regency and the general public who can provide information on the location of road equipment, as well as road equipment complaints services. Keywords:GIS; Geographic Information System; Extreme Programming

The streak tube imaging lidar (STIL) system is a new 3D imaging technology that can obtain a complete frame image of the target with only one laser pulse and it has many advantages such as high frame rate, big field of view and so on over the scanning-mechanism system. The principle of the experiment will be introduced firstly and the pre-process of the data will be simply discussed, such as correction of image distortion, the noise filter and image enhancement, data segmentation and so on. All the methods to the above data pre-process are specially adopted for the STIL system. The range of the target, the time of the photoelectron flight and the range of the target image on the phosphor screen have a linear relationship and it will be proved; according this, a mathematical model to reconstruct the 3D image is put forward and the algorithm to calculate the relative range of the target is confirmed. Based on the model and the algorithm, a program in the VC++ and matlab environment to analyze the lidar data, reconstruct and display the 3D image of the target is compiled. The result verifies the model and the algorithm effective.

Automatic Wire

Today's multipurpose wire bonding machines are required to deliver a combination of wires, bumps, and specialty interconnects for RF, automotive, and optical markets with odd-form factor parts. These market production requirements are generally lower volume with a higher mix of products compared to typical high-volume semiconductor packaging of memory and logic. These markets also require multipurpose wire bonders to accommodate large work area, deep access, and a complex mix of bond surfaces, wire shapes, and bumps. The number of components in a package can vary from one with a few wires up to hundreds of components with thousands of wires. Programming methods, process development, traceability, and rework are different for customers using this class of bonder. A survey of customer application cases shows the range of capabilities available to packaging engineers. The four primary cases presented highlight the range of applications that can be handled for odd-form factor packages and specific areas of focus to maximize productivity for these classes of products.Case 1: Ball Bump Size and Shape Examples: acheiving 119μm down to 44μm bonded ball diameters and range of shapes.Case 2: Ambient Wire Bonding to a 6″ Tall Package: demonstrating allowable bonding volume and tooling flexibility plus the ability to bond Au with substrates at ambient temperature.Case 3: Batch Load Tray (Mechanical and Vacuum Clamping): allowing quick change over for radically different sized packages.Case 4: Complex High Part Count Packages: supporting alternate parts and alternate bonding wires, stand-off stitch, and security bonds require special features for programming and navigation methods to allow easy creation and navigation of complex programs for maximum productivity. Breakdown of timing and efficiency is provided showing programming efficiencies of 2X or better. These cases will help packaging engineers extrapolate to their own cases and show how a multipurpose automatic wire bonder can be an effective way of automating or semi automating these manually or automatically presented packages for higher throughput, higher quality and consistency, and less labor usage for lower cost.

Projection Angle

Three-dimensional (3D) microstructure visualization on the electron microscope requires that the sample be tilted to different positions to collect a series of projections. This tilting should be performed rapidly for on-line stereo viewing and precisely for off-line tomographic reconstruction. Usually a projection series is collected using mechanical stage tilt alone. The stereo pairs must be viewed off-line and the 60 to 120 tomographic projections must be aligned with fiduciary markers or digital correlation methods. The delay in viewing stereo pairs and the alignment problems in tomographic reconstruction could be eliminated or improved by tilting the beam if such tilt could be accomplished without image translation.A microscope capable of beam tilt with simultaneous image shift to eliminate tilt-induced translation has been investigated for 3D imaging of thick (1 μm) biologic specimens. By tilting the beam above and through the specimen and bringing it back below the specimen, a brightfield image with a projection angle corresponding to the beam tilt angle can be recorded (Fig. 1a).

This paper presents strategies for increasing the effectiveness and efficiency of the school-based speech-language pathologist. Various time management strategies are adapted and outlined for three major areas of concern: using time, organizing the work area, and managing paper work. It is suggested that the use of such methods will aid the speech-language pathologist in coping with federal, state, and local regulations while continuing to provide quality therapeutic services.
