Model-Based Development Process of Cybertronic Products and Production Systems

The shift to satisfied customer markets forces manufacturers to offer customised products. Moreover, product lifecycles are shortened, which requires a faster development of products and corresponding production systems. Both challenges amplify complexity in production. This complexity is usually confronted with flexibility. A new approach offering decentralised structures, and thereby flexibility, comes from cybertronic systems (CTS), which are further developed mechatronic systems with the capability to communicate through open networks with other such mechatronic systems. Up to now no integrated development process to engineer cybertronic products (CTP) and production systems (CTPS) has been developed, although such a process is essential to use their beneficial properties for today’s market conditions. Therefore, research is conducted in the research project mecPro². First, the properties of cybertronic systems are investigated and dissociated from those of mechatronic systems. Based on these properties, the connections of CTP and CTPS are analysed and a systematics for description for both is identified. With this the model-based development processes of CTP and CTPS can be further defined as well as their intersections and afterwards implemented in a data model. Finally, the development process is summarised in a product lifecycle management software to support the development process.
Power system disturbance patterns

The author presents some power system disturbance patterns that were obtained by continuously monitoring the power supply of a computer system over a period of two years. An examination of the undervoltage disturbance patterns over this two-year period revealed that the majority of disturbances occurred during normal working hours (8 am-5 pm). The characteristic patterns were different from year to year (i.e., similar shape but significantly different frequencies of occurrence). The number of samples in which no disturbances were recorded decreased as the duration of site monitoring increased. The frequency of undervoltage power supply disturbances was strongly correlated with the seasons, and the mean time between undervoltage power supply disturbances was 39.54 h. Each type of power supply disturbance exhibited unique patterns of occurrence with significantly different mean times between disturbances. <<ETX>>
Design of a Wave Shifter with the Exit Direction Controllable Based on Coordinate Transformation Theory

We propose a wave shifter with the exit wave direction controllable by using a transformation-medium slab. The coordinate transformation takes two steps. One is along the longitudinal axis to realize shift and the other is on the transversal axis to adjust the exit directon. By using coordinate transformation theory, the constitutive parameters of the slab are obtained. Numerical simulations are further given to validate the performance of the theoretical design.
TIPP 2011-Technology and Instrumentation in Particle Physics 2011 The Next Generation Scintillator-based Electromagnetic Calorimeter Prototype and Beam Test

We are studying next generation scintillation detectors for future collider experiments. For precise energy measurement of energetic jets in future experiments, particle flow algorithm with fine granular scintillator strip calorimeter will play an important role. To establish the technology of the calorimeter, we are studying the properties of small plastic scintillator strips with size of (10-5) x 50 x 3 mm, which is a fundamental component of the calorimeter. As a part of this R&D study, small extruded plastic Scintillator of size 10 x 45 x 3 mm and a tungsten plate with 3.5 mm thick are sampled together to Fabricate a Scintillator base electromagnetic calorimeter prototype. Prototype has a stack of 30 layers, having dimension of 20 x 20 cm. Fine Scintillator strips in successive layers aligned in orthogonal to achieve effective 1 x 1 cm segmentation. The total number of channels is 2160 for readout. scintillation light produced in plastic Scintillator strips enters the wavelength shifting (WLS) fiber placed inside the plastic Scintillator are guided to the sensitive photo detector 1600 pixel MPPC (Multi Pixel Photon Counter) with a sensitive region of 1 x 1 mm. The electromagnetic calorimeter performance has been studied with test beam during summer 2008 and 2009 at Fermilab. We have injected 1-30 GeV electron and 60 GeV Pion beams and measured energy resolution and linearity of response toward input energy. In this presentation we will present obtained performance of the calorimeter prototype. © 2011 Elsevier BV.

Identification of parameters and structure of piecewise affine models of genetic networks

In this paper we consider piecewise affine models of genetic regulatory networks proposed by Glass and Kaufmann in the 70's and discuss a method for their identification. These systems have specific features that must be preserved by the identification procedure in order to obtain biologically meaningful models. Moreover, rather than producing a single hypothesis about the way genes interact, identification should produce alternatives consistent with the available data so as to provide biologists with multiple hypothesis about the network functioning. The input of the identification method consists of time-series measurements of concentrations of gene products. As outputs, estimates of the modes of operation of the GRN as well as all possible minimal combinations of threshold concentrations of the gene products accounting for switches between the modes of operation are provided. Individual steps of the identification method have been been described separately in previous publications and the main aim of this paper is to test the applicability of the whole procedure. To this purpose, we use simulated data obtained from a model of the carbon starvation response in the bacterium E. coli. In particular, performance of the method under different data characteristics, notably variations in the noise level and the sampling density, are discussed.
Nutritional-Medicinal Profile and Quality Categorization of Fresh White Button Mushroom

Due to susceptible change era for the world, limited land resources; vast encounter to meet the food demand and medicine for the growing populations make the necessity to discover any alternative food which has good nutritional and medicinal value. Hence, the quality categorization of Fresh White Button Mushroom has been necessitated by the need for harmonizing requirements governing the quality of products. The contents and categorizations were formulated in accordance with the procedures established by standards physiochemical and sensory determination methods. The chemical composition (moisture, ash, protein, carbohydrate, total fat) and minerals composition (Se, Ni, Mn, Cu, Zn, Na, N, Fe, P, Ca, Mg, S, and K) of white button mushroom were determined. Results show that edible mushrooms are rich sources of protein (3.27±0.12), fiber(1.87±0.08), carbohydrates (2.66±0.61), fats (0.22±0.05) and energy (28.50±1.22 Kcal) g/100g fresh weight basis respectively. In addition to these, white button mushrooms also contain the highest content of potassium (3560±153.33) and sulfur (2195.59±1405.60) mg/kg fresh weight basis mineral elements. The quality categorization was monitored under a controlled environmental condition (Temp. 5-6±10C) and packed in a 30µm thickness polyethylene bag. The data were categorized by organoleptic, physicochemical, and bacterial count (CFU/g) basis. The grades SSQM: size<33.44mm, whiteness(Hunter) >80 number of pieces: 19/200g, open veils; Nil, Veiled: Nil; lactic acid: > 0.7%, Lactococcus lactis: >9.5x105,SQM: Size range of 33.57-38.55,whiteness (Hunter):70-80,Veiled 1, open veiled 1, open veiled 6.25%, lactic acid: 0.4-0.7 % and Lactococcus lactis: > 8.4 x 105, AQM: size>38.62, Whiteness (Hunter): 60-70,Veiled 1, open veiled 2, open veiled 16.6%, lactic acid: 0.3-0.4 % and Lactococcus lactis:>3.4 x105. The overall fruiting body has a significantly high level of nutrient and mineral composition, Lactic acid, and probiotic bacteria, thus WBM can be used as a good source of food as well as medicine.

Titanium alloys are commonly used in industry, automotive, medical and all manufacturing applications.Unconventional machining process which offers lesser micro structural changes and less internal stresses produced during machining compare to traditional machining process. In this project Titanium Grade 5 alloy is machined by using WEDM process with different feed rates and the mechanical property changes are to be investigated. WEDM has since the process' launch emerged as the best option to manufacture micro parts with the highest degree of dimensional precision and surface finish consistency from a simple way to manufacture instruments and die. The machining parameters like kerfs width, material removal rate, feed rate, wire speed, wire tension and voltage are the factors influencing the mechanical properties and micro structure changes. Out of these parameters, the feed rate is varied and the properties like hardness, surface finish and micro structure changes are to be investigated and the best suitable feed rate for machining the titanium grade 5 alloy is to be identified.
Challenges in neuro-machine interaction based active robotic rehabilitation of stroke patients

【Study results in the last decades show that amount and quality of physical exercises, then the active participation, and now the cognitive involvement of patient in rehabilitation training are known of crux to enhance recovery outcome of motor dysfunction patients after stroke. Rehabilitation robots mainly have been developing along this direction to satisfy requirements of recovery therapy, or focusing on one or more of the above three points. Therefore, neuro-machine interaction based active rehabilitation robot has been proposed for assisting paralyzed limb performing designed tasks, which utilizes motor related EEG, UCSDI (Ultrasound Current Source Density Imaging), EMG for rehabilitation robot control and feeds back the multi-sensory interaction information such as visual, auditory, force, haptic sensation to the patient simultaneously. This neuro-controlled and perceptual rehabilitation robot will bring great benefits to post-stroke patients. In order to develop such kind of robot, some key technologies such as noninvasive precise detection of neural signal and realistic sensation feedback need to be solved. There are still some grand challenges in solving the fundamental questions to develop and optimize such kind of neuro-machine interaction based active rehabilitation robot. 】
Short feedback loop for OPC model based on wafer level CD

A calibrated Optical Proximity Correction Model (OPC) allows the accurate prediction of wafer printing results based on the geometrically defined layout of features. Therefore the OPC Model takes physical parameter of the mask, optical parameter of the printing system and chemical parameter of the resist into account. In order to find a good correlation between OPC simulated data and real wafer prints, the mentioned parameter needs to be calibrated. In the past, this calibration was done based only on the wafer CD SEM measurements. To speed up the calibration process, this paper investigates the possibility to use the aerial image measured by a wafer level critical dimension measurement tool (WLCD) to shorten the feedback loop and to reduce the amount of wafer prints needed for calibration.
A laser measurement system with multi-degree-of-freedom

A new five-degree-of-freedom measuring system was developed as a linear guide. According to the principle of autocollimation, the system consisted of two semiconductor lasers, two right angle prisms, two lenses, two polarization spectroscopes and four quadrant Si-photoelectric detectors(QPD). Two axial displacements and three angular rotation degrees are measured by comparing the position of the spot center on the QPD. Repetitive simulations show that the accuracy of the system is 3" for measurement of angle, which proves the feasibility of this system. The advantages of the system include simple structure, easy operation, high accuracy, low cost and real-time work.
Power Factor Corrector Based on Parallel Quasi- Resonant Pulse Converter with Fast Current Loop

Abstract The problems, devoted to power quality and particularly power factor correction, are of great importance nowadays. The key requirements, which should be satisfied according to the energy efficiency paradigm, are not limited only by high quality of the output voltage (low total harmonic distortion), but also assume minimal power losses (high efficiency) in the power factor corrector (PFC). It could be satisfied by the use of quasi-resonant pulse converter (QRPC) due to its high efficiency at high switching frequency instead of the classical pulse-width modulated (PWM) boost converter. A dynamic model of QRPC with zero current switching (ZCS) is proposed. This model takes into account the main features of QRPC-ZCS as a link of a PFC closed-loop system (discreteness, sharp changes of parameters over switching period, input voltage impact on the gain). The synthesized model is also valid for conventional parallel pulse converter over an active interval of commutation. The regulator for current loop of PFC was synthesized based on digital filter using proposed model by the criterion of fast acting.
The reduction in plant maintenance costs using creative problem-solving principles

Abstract The paper considers the application of creative problem-solving (CPS) principles to the reduction of plant maintenance costs. A brief description of CPS principles and methods is first given. Three case studies are then described that illustrate the use of CPS on problems at plant and machine levels, by different group compositions and on problems of different types. A review of experience of the use of CPS methods by maintenance engineers trained in their use is also given. It is concluded that CPS is a valuable approach that may be used effectively to identify causes of maintenance problems and to find solutions to particular problems of diverse kinds that incur maintenance costs.
Variations between Foundation-Level and Free-Field Earthquake Ground Motions

Strong motion data from sites having both an instrumented structure and free-field accelerograph are compiled to evaluate the conditions for which foundation recordings provide a reasonably unbiased estimate of free-field motion with minimal uncertainty. Variations between foundation and free-field spectral acceleration are found to correlate well with dimensionless parameters that strongly influence kinematic and inertial soil-structure interaction phenomena such as embedement ratio, dimensionless frequency (i.e., product of radial frequency and foundation radius normalized by soil shear wave velocity), and ratio of structure-to-soil stiffness. Low frequency components of spectral acceleration recorded on shallowly embedded foundations are found to provide good estimates of free-field motion. In contrast, foundation-level peak ground acceleration (both horizontal and vertical) and maximum horizontal velocity, are found to be de-amplified. Implications for ground motion selection procedures employed in attenuation relations are discussed, and specific recommendations are made as to how these procedures could be improved.
Optimum diversity separation for over-sea line-of-sight radio links

Given the requirement for a line-of-sight link operating over a sea path and having established the clearance at the horizon over the appropriate range of k-values using standard procedure, a method is derived for determining the optimum spacing for worst case conditions between receiving antennas where dual space diversity is employed to reduce 2-path fading. The means of calculating the minimum received signal, i.e. the deepest fade possible with destructive interference in the 2-path mode, is also included; as a check on performance if the optimum spacing cannot be realized or where the optimum value is used and the worst case conditions assumed in this determination do not apply in practice.Programs for these calculations are included which run on TI58 or TI59 pocket calculators. A third program for the calculation of Fresnel zone numbers (cubic equation solution) is included. The method is valid for any frequency band in which line-of-sight criteria apply and 2-path propagation occurs.Although consideration of the probability of occurrence of any particular propagation mode lies outside the scope of this paper, it is found that the correct 2-path diversity spacing also provides substantial protection in other adverse propagation circumstances.
Wind-Tunnel Fire-Whirl Experiments Using a Scale Model

This short communication proposes a new scaling law, on the basis of which scale-model experiments on a large-scale wind-aided fire phenomenon can be designed. The proposed scaling law takes into account the Froude number, which is defined using the flame height. The results of two different scale-model experiments on the fire whirls observed after the Great Kanto Earthquake are reported. The wind velocities in the scale-model experiments are determined using the proposed scaling law. The scale-model experiments successfully reproduce fire whirls similar to those observed after the Earthquake, thus validating the proposed scaling law.
Response Criterion Placement Modulates the Benefits of Graded Alerting Systems in a Simulated Baggage Screening Task

An experiment compared the benefits of two-level and graded alerting systems as human performance aids in a simulated baggage x-ray screening task. Decision boundaries for the graded systems were varied to produce an unhesitant aid, one which rendered a diagnostic judgment on a majority of trials, and a hesitant aid, one which rendered a judgment on only a minority of all trials. Judgments from the aid were rendered as text messages preceding each trial. The participants' task was to search for threat objects in simulated baggage x-rays; true target presence rate was 50%. The unhesitant three-level aid significantly improved human performance relative to an unaided control condition, and produced better human performance than either the hesitant three-level aid or the two-level aid. The benefits of the unhesitant three-level system arose from the human operators' increased willingness to act on the aid's diagnoses. Results carry implications for the design of automated diagnostic decision aids for security screening and similar signal detection tasks.
Linear Stability Of Relativistic Space-Charge Flow In A Magnetically Insulated Transmission Line Oscillator

The magnetically insulated transmission line oscillator (MILO) is a high power microwave device that combines the technologies of magnetically insulated electron flow and slow-wave tubes. This combination makes the MILO a unique and robust device capable of operating over a wide range of voltages. Microwaves are generated in the MILO via an unstable interaction between slow electromagnetic modes and space-charge waves. We present a linear analysis of this microwave instability that includes the physics of magnetically insulated electron flow. A dispersion relation is derived for transverse magnetic (TM) modes in a cylindrical MILO. The dispersion relation is solved numerically to obtain the MILO frequency spectrum and instability growth rates. We compare the linear theory results with numerical simulation, and obtain excellent agreement.
Multi-pose ear recognition using locally linear embedding and nearest feature line

Multi-pose ear recognition is a challenging problem of ear recognition technology. In this paper, the method based on locally linear embedding (LLE) and nearest feature line (NFL) is proposed by analyzing the disadvantages of most 2D ear recognition methods currently when dealing with poses variation and the shortcomings of the nearest neighbor (NN) classifier. The LLE algorithm is used to extract the ear feature, and then the NFL classifier is applied to classify ear images under varying poses. By contrast, experimental results show that the method based on LLE and NFL can obviously improve the recognition performance, which demonstrates the validity of this method.

Formal design and analysis of a hybrid supervisory control structure for Virtual Production Systems

Virtual Production Systems (VPSs) is a dynamic paradigm for production resources structure, which was proposed to cope with changing and uncertain manufacturing environment. However, the high performance of VPSs relies on a high-quality control in practice. Motivated by both local quick responses and global optimization, a supervisory control structure based on autonomous and coordination mechanisms is proposed for VPSs in this paper. This hybrid supervisory control structure is formally designed and analysed with timed automata on the platform of an integrated tool named UPPAAL. First, the Discrete Events Dynamic Systems (DEDS) model of VPSs is established. Then autonomous and coordinated supervisory controllers are further designed under the guidance of heuristic scheduling rules, such that the desired characteristics of both performance (production flow and time) and activity (overflow-, conflict- and deadlock-free) can be ensured. Finally, system analysis, including deadlock-free analysis, calculation and simulation of time-optimal scheduling, is made through verification. A case study is made to illustrate that control and scheduling can be well integrated into this hybrid supervisory control structure in practice.
