DECODING A VCR CONTROLLER CODE

The VCR Plus+ is a remote control for programming video cassette recorders. It uses an encrypted 1 to 8 digit number that encodes the channel, start time, length, and day of the month of the television show to be recorded. This paper describes a procedure for decoding the 1 to 6 digit codes.     

Gourdron theory: revealing synthetically the masses for biological molecular particles of DNA and proteins and abiological particles of quarks and leptons

In the present report, we examine whether or not there are similar and different characteristics between biological molecular particles and non-living ones such as quark and leptons. While the Newton, Schrodinger, and Boltzmann equations and elementary particle theories describe only a narrow range of scales, the present statistic-fluid dynamic theory having only one arbitrary constant synthetically reveals masses as well as frequencies of various particles of quarks, leptons, W–Z bosons, Higgs boson, plank mass, hadrons, atoms, biological molecules, liquid droplets, living cells, biological organs, and stars. This is possible because each flexible particle is commonly generated by a mode in which a larger particle breaks up into two smaller ones through a gourd shape (gourdron) with two lumps rather than strings. These masses and frequencies dominated by the super-magic numbers, including the asymmetrically golden and symmetrically yamato ratios, can be derived by a quasi-stability principle weaker than neutral stability. The primordial mechanism underlying various types of symmetry breaking and the natural four forces including gravity is also revealed by this theory.     

Locomotion Control of MEMS Microrobot Using Pulse‐Type Hardware Neural Networks

This paper presents the locomotion control of a microelectromechanical system (MEMS) microrobot. The MEMS microrobot demonstrates locomotion control by pulse‐type hardware neural networks (P‐HNN). P‐HNN generate oscillatory patterns of electrical activity like those of living organisms. The basic component of P‐HNN is a pulse‐type hardware neuron model (P‐HNM). The P‐HNM has the same basic features as biological neurons, such as the threshold, the refractory period, and spatiotemporal summation characteristics, and allows the generation of continuous action potentials. P‐HNN has been constructed with MOSFETs and can be integrated by CMOS technology. Like living organisms, P‐HNN has realized robot control without using software programs or A/D converters. The size of the microrobot fabricated by MEMS technology was 4 × 4 × 3.5 mm. The frame of the robot was made of a silicon wafer, equipped with rotary actuators, link mechanisms, and six legs. The MEMS microrobot emulated the locomotion method and the neural networks of an insect by rotary actuators, link mechanisms, and the P‐HNN. We show that the P‐HNN can control the forward and backward locomotion of the fabricated MEMS microrobot, and that it is possible to switch its direction by inputting an external trigger pulse. The locomotion speed was 19.5 mm/min and the step size was 1.3 mm. © 2013 Wiley Periodicals, Inc.

Determination of dyers’ perceived components of colour difference (depth,brightness and hue) between two similar colours from their spectral reflectance values

The partitioning of colour differences into ΔL^*, ΔC^* and ΔH^* is not directly equivalent to the dyer’s method of partitioning. The dyer’s method involves separation into the components of depth (ΔD), brightness (ΔB) and hue (ΔH), of which only hue difference has a qualitative (and quantitative) equivalent in the CIELAB system. Depth and brightness are important terms to dyers. Depth is related to the amount of dye taken up by a textile material and brightness to that component of colour difference that is neither depth nor hue. Brightness is best defined as the opposite of dullness, dullness being related to the amount of neutral grey present in the colour. An algorithm, called the Wardman–Smith–Farooq algorithm, has been developed to compute the dyers’ variables of ΔD,ΔB and ΔH from spectral reflectance values, enabling dyers to take full advantage of colorimetry. The algorithm is based on extensive experimental work to map surfaces of constant visual depth through the colour space and this paper describes the methodology of the calculation. The correlations of the values of ΔD,ΔB and ΔH, determined using the Wardman–Smith–Farooq algorithm with other empirical models for 117 sample pairs, are given.     

Decomposition Characteristics of an Artificial Biogas in a Low‐Pressure DC Glow Discharge

The decomposition characteristics of an artificial biogas, which is a mixture of CH ₄, CO ₂, and H ₂ S, using a low‐pressure DC glow discharge have been investigated. It is found that H ₂, CO, C ₂ H ₂, H ₂ O, CS ₂, and COS are produced from the artificial biogas in the glow discharge. About 65% of the hydrogen atoms in CH ₄ are converted into H ₂ at an input energy of 800 J, at which CH ₄ is completely decomposed, and the decomposition characteristics of the artificial biogas are minimally dependent on the H ₂ S additive. Further, H ₂ S has a tendency to be decomposed earlier than the other components of the artificial biogas. When the glow discharge is generated in the artificial biogas with H ₂ S, some of the carbon atoms are found to deposit on the electrodes and the wall of the discharge chamber. © 2013 Wiley Periodicals, Inc.

Analysis of the Microstructure of Mg2Si Thermoelectric Devices

High-performance Mg₂Si thermoelectric devices have been obtained by spark plasma sintering of high-purity, pre-synthesized, all-molten Mg₂Si powder. We studied the effects of source powder particle size on thermoelectric performance. To improve the performance, further investigation of the microstructure of the devices is needed. In this work we studied the microstructure of grain boundaries and interfaces between electrodes and Mg₂Si sintered bodies to increase understanding of Mg₂Si thermoelectric devices.     

Discovery of functional protein groups by clustering community links and integration of ontological knowledge

In this paper we cluster data from protein networks and integrate the results with chemical databases and ontologies to investigate functional links between related disease states. It is well know that certain genes participate in more than one function and if they are defective are likely to be responsible for several health problems. Furthermore, genes tend to cooperate in associated networks or cascades often with ’crosstalk’ between networks which can subtly alter cellular functions. Understanding the complexity and role of the various cell functions and mechanisms requires the use of computational models to make inferences and link together the interplay between genes, proteins and chemical interactions. A deeper understanding of the mechanisms of diseases will eventually be of benefit for the development new and improved therapies. The particular disease state we investigate in this work is cystinosis which is characterized by the widespread deposition of the amino acid cystine in cells due to a defect in cystine transport. In cystinosis, cystine accumulates in the lysosomes and eventually forms crystals throughout the body causing problems in the kidneys and the eyes. The defect is caused by a mutation in the CTNS gene and this forms the starting point for our investigation.
