We have produced a new, automated Maszara testing tool. This tool can be used to measure the bond strength across the entire interface of a bonded wafer pair and produce a bond strength map. The tool can also be used for IR inspection.
Urine is waste that must be discharged from living bodies. In the medical field, urine is very useful for analyzing and curing diseases. The kidneys extract waste from the blood. Urinalysis is used to determine and inspect urinary function and system. This research developed an analytical System for a Urine Strip Test Using Image Processing to compare among human eyes and Urine automated with 100...
We study in this paper an authorship attribution in Arabic poetry using text mining classification. Several features such as Characters, Poetry Sentence length; Word length, Rhyme, Meter and First word in the sentence are used as input data for text mining classification algorithms Naïve Bayes NB, Support Vector Machine SVM, and Sequential Minimal Optimization SMO. The data set of experiment was divided...
Point-of-care testing (POCT) has transformed the healthcare landscape by delivering quick and cheap diagnostic services closer to the patient. Urine test strips are one of the most commonly used POCT tools, however their manual interpretation can be challenging, particularly for the elderlies and people with eye disorders. In this study, we propose a smartphone application designed to automatically...
We present a novel methodology for automated ABO Rh-D blood typing using simple morphological image processing algorithms to be used in conjunction with a fabric strip based rapid diagnostic test. Images of the fabric strip post testing are acquired using low cost mobile phones and the proposed algorithm proceeds to automatically identify the blood type by processing the images using steps comprising...
Despite the importance of the random testing approach, random testing is not used in isolation, but plays a core role in many testing methods. On the basis that evenly distributed test cases are more likely to reveal non-point pattern failure regions, various Adaptive Random Testing (ART) methods have been proposed. Many of these methods use a variety of distance calculations, with corresponding computational...
A variant of Adaptive Random Testing (ART) called Centroid Based Adaptive Random Testing (CB-ART) has been developed. It aims to improve efficiency of ART which was claimed to have better performance than Random Testing (RT) in finding first error in a program. CB-ART is applying the concept of centroid for test case selection process. The technique for generating and computing centroid from a pool...
This paper presents a new mathematical model and solution technique for horizontal wells in two-zone linear composite infinite reservoirs which are assumed to be isotropic in each one of the two zones. The model is solved by using Fourier and Laplace transformation. Based on Duhamel principle, wellbore storage and skin effects can easily be incorporated. Pressure respond curves are plotted with Stehfest...
This paper proposes a working model of a bilingual OCR system for printed Thai and English text with word prediction technique. The main idea is that instead of recognizing individual characters from an image block as the conventional approach, it attempts to match the whole word from a list of predictive words based on n-gram trees. The matching process is done in the stage of word verification,...
In this research, commissioned by the manufacturer, the IDEO design process is employed to improve the old glucose meters. Through interviews with the stakeholders, we found out the demands of the client and determined the market positioning and design style using perceptual map. By analyzing the modeling language of the leading brands, we conducted an in-depth design research and usability testing...
Louisiana Tech University in partnership with three local high schools has recently developed NASA-Threads, a high school curriculum that integrates engineering, mathematics, and physics. The curriculum uses hands-on projects that develop student ability to solve realistic multiple-step problems and bring excitement into the classroom. One of the projects implemented in the “Work and Mechanics” portion...
This article proposes a robust set-membership fault detection method based on the use of polytopes to bound the parameter uncertainty set. The proposed polytope-based fault detection algorithm is able to handle systems with bounded parameter variation between samples. It is shown that consistency checks indicating faults can be performed in a natural manner with a polytope description of the feasible...
In this paper, a type of improved hybrid strategy is used to carry out the image segmentation of gold immuno chromato graphic test strip, which combines the reactive tabu search (RTS) algorithm and error back propagation (EBP) neural network. This hybrid strategy can solve the problems which exist in image segmentation of test strip: the area of test strip is pretty small; the breadth of test line...
This paper presents analysis of a proposed mechanical design solution for improving the downcoiler operations on a hot strip steel rolling mill. The design solution incorporates a novel pneumatic/hydraulic hybrid cylinder, used to hold the downcoiler wrappers in position to guide the steel strip whilst coiling. A full size testing rig was constructed to fully test the new prototype cylinder. The data...
A pocket device for rapid combined test of biomedical samples is comprised of four parts: strip, strip attached column, sampling head and test tube. One to multiple strips are separately attached to the shallow groove on the surface of the strip attached column. The strip attached column is placed inside the test tube of the device. The sampling head is in front of the test tube. The sampling head...
Adaptive Random Testing (ART) is a testing technique which is based on an observation that a test input usually has the same potential as its neighbors in detection of a specific program defect. ART helps to improve the efficiency of random testing in that test inputs are selected evenly across the input spaces. However, the application of ART to object-oriented programs (e.g., C++ and Java) still...
As there still exists a gap in the design of the rumble strips, the author in this paper takes Tiema heavy-duty lorry as the typical vehicle and uses the simulation model established by ADAMS (automatic dynamic analysis of mechanical system) dynamic simulation software to analyze the changing laws in the mean square root of the rumbling acceleration with the three designing factors on the basis of...
The objective of this experiment is to create a device that will maintain the integrity of the mandible and maxilla in edentulous patients. The absence of mechanical force on the bone induces resorption, increasing fracture risk. Ultrasound transducers will be used to simulate the mechanical stress normally induced by teeth through the propagation of ultrasound into the bone. As a result, the Wnt...
Recently there have been several developments in the areas of small form factor and high-density lead frame based IC packages. These packages have the benefits of occupying smaller PC board area, lower assembly material consumption due to their smaller volume package construction, and good thermal dissipation properties. Another area of recent development in packaging integration is system in package...
Time-frequency domain features of chest compression (CC) artefacts, non-shockable (NShR) and shockable (ShR) rhythms were investigated. The aim was to provide reliable shock advisory analysis during CC by single channel electrocardiogram (ECG) processing. Three frequency bands were suggested to enhance specific components of the CC artefacts, NShR and ShR rhythms: (i) 2-3 Hz to emphasize the similarity...
