The reliability of aircraft electrical components directly affects the combat performance of the aircraft. But the reliability is determined by the design, processing, environmental factors, accidents and other factors. Environmental testing is to prove the reliability and processing. According to the failure characteristics of electrical components, We have developed hot-humid, salt spray, mildew...
Along with the change of troop's assignment and the mode of missile equipments' application, the work of deployed equipment's logistics support has changed a lot. Supportability demonstration also becomes an important job in the course of the missile equipments' developing, manufacture and deployment, and it has become the foundation of the missile materiel's research about Integrated Logistics Support...
It is often of interest to be able to determine the technical life of a product. Especially during the development of a new product but also for already existing products.
An important question is how to determine if a person is exhibiting suicidal tendencies in behavior, speech, or writing. This paper demonstrates a method of analyzing written material to determine whether or not a person is suicidal. The method involves an analysis of word frequencies that are used in a fuzzy cognitive map. The fuzzy cognitive map determines if there are suicidal tendencies. The method...
Particleboard being the main building material for kitchen cabinet in Malaysia houses has shown some installation problems. The damages observed during installation are in the form of split holes, loose holes and delamination. Almost all of the sites visited have shown some damages of the particleboard during the screw fixing activities. Screw-holding performance test was done in the same condition...
Objective To establish a rapid identification method for electrolyte material adulteration in raw milk, and was used for inspect raw milk. Methods Through the chromogenic reaction with specific chemical reagents, the adulterated electrolyte materials such as salt, nitrite, nitrate, sulfate, sodium thiocyanate, alkali were identified qualitatively. Results The method of inspection electrolyte material...
There are more than 55 kilometers subgrade in NGZQ-5 section of Nanning-Guangzhou high-speed railway passenger dedicated line. A large number of filling material along the construction section is high expansive clay soil, and it must be improved by physical or chemical methods. The liquid and plastic limits, expansibility, mechanical strength and water stability of expansive soil is studied. The results...
Nanocomputing and related-enabling technologies hold the promise of higher performance and lower power consumption, as well as increased communication capabilities and functionality. In addition to the impact on today computerized systems, nanocomputing is an essential lever to foster the emerging cyberphysical system paradigm. However, the dependability and security of these unprecedentedly small...
In the traditional photoelastic experiment, We have to get isochromatic and isoclinic stripes, to be a very tedious work. Most of the work requires manual operation to complete, low efficiency, low precision, thus limiting the accuracy of results. This article uses a digital photoelastic image processing method, using phase shift technique, re-derivation and demonstration of the phase difference formula...
An improved Tungsten light source system for photo voltaic cell testing constructed from low-cost, commercially available materials is presented as an alternative to current high-cost solar simulators. In this work, spectral correction of the Tungsten light source is achieved by increasing the colour temperature to ~5200 K using inexpensive commercially available filters. Spectral measurements of...
In order to promote to share resource of Agricultural Information Courses (AIC) for our school master's network education, ensure teaching quality and improve the construction level of the network courses; we have developed a teaching demonstration system. This teaching platform can reform the traditional agricultural informatization instruction, and improve the teaching and research activities of...
The Computational Imaging and Biomechanics Lab(CIBL) at Drexel University has been continuously researching the mechanical properties of soft tissues, specifically tendon and heart valves. Our current effort is on a new testing device scaled down for individual fascicles also known as the mesostructure-scale. This paper presents preliminary results of that system capturing the properties of electrospun...
This paper discusses why it is necessary for new lower cost PV modules to be tested using a reliability test sequence that goes beyond the Qualification test sequence now utilized for modules. Today most PV modules are warranted for 25 years, but the Qualification Test Sequence does not test for 25-year life. There is no accepted test protocol to validate a 25-year lifetime. This paper recommends...
DRS-1 high normal stress direct and residual shear apparatus was used to study the direct shear mechanical characteristics of the sand with different granular diameter under different normal stress. The results show that for three kinds of sand (coarse sand, medium sand and fine sand) the curve of shear stress-shear displacement presents strain softening when the normal stress, σ, is less than, or...
PCL foams were fabricated and tested mechanically and observed via scanning electron microscopy for use in future studies to elucidate the interactions between tissue engineered scaffolds and host tissue following implantation.
The dynamic properties of the circular saw blade when cutting at a high speed influence the cutting quality at a large extent. This paper gives a brief introduction about the employment of advanced sensors and detection methods together with self-detection software system detect circular saw blade vibration quickly and accurately, non-destructively at the condition of high-speed rotating of the circular...
Non-destructive evaluation (NDE) is an effective and reasonable technology for utilization in wooden material. Facing the defects of wooden material, the effective NDE appears practically significant for protecting wood structures. Major NDE techniques and equipments applied in wood structures detection were systematically summarized. Then State of main researches on NDE used in wooden material was...
The Local Energy Alliance Program (LEAP) has been investing its efforts in convincing homeowners in Charlottesville, Virginia to renovate their homes for reduction of energy consumption. Although LEAP had conducted a focus group, which emphasized comprehending homeowners' perceptions about home energy efficiency renovations, and determined several potential incentives that could lead homeowners to...
