Analytical Applications of 3-D imaging in Vehicle Accident Studies

Three-dimensional (3-D) computer imaging and animation have been widely used in industrial design. The use of computer imaging and animation for illustration in the court room has been widely recognized. Three-dimensional computer animation also has analytical uses that apply to the accident reconstruction field. It can be used to evaluate visibility, timing of complex motions, and is helpful in correlating vehicle damage to ground strikes. Used in concert with photogrammetry, 3-D imaging can be very useful in determining the positions of objects pictured at the accident scene.

Marine gas turbine performance diagnostics: a case study

Summary The paper discusses how performance models can be used for marine gas turbines. A particular performance model, built for on board training purposes is employed to demonstrate the different aspects of this process. The model allows the presentation of basic rules of gas turbine engine behavior and helps understanding different aspects of its operation. A smart designed graphics user interface is used to present engine operation in different ways: operating line, operating points of the components, interrelation between performance variables and parameters etc. The perception of fault signatures on monitoring parameters is clearly demonstrated. Diagnostics capabilities of the existing performance model installed at the Hellenic Naval Academy Gas Turbines Virtual Lab are examined and tested using the measurement data from real marine gas turbines. A case study is discussed in this paper where the model results and the real engine conditions are compared for diagnostic purposes.

Transmitters interference to victim receivers and radiation hazards human

Nowadays, radio system transmitter (Tx) harmful interference and radiation effects are significantly important and complex. A very important issue is the requirement for coexistence of transmitters (Tx) and receivers (Rx) on the same site (cosited), where radio mutual interference and radiation hazards are significantly more important than from internal, natural and industrial noise effects. Results show that under some cosited scenarios when victim Rx are blocked or strongly desensitized by high power interfering Tx. Persons located in the proximity of the Rx may be affected by radiation intensity which may approach the standard threshold limits. Thus, we can conclude that in special cases, described in this paper, a correlation exists between Tx's interference to victim Rx and radiation intensity level to exposed human. However it is important to emphasize that the sensitivity of Rx to Tx high power interference is significantly higher than the sensitivity of exposed people to radiation effects.
Trajectory Optimisation and Feedback Control for the YES2 Tether-assisted Re-entry Mission

YES2 (launching 2007) aims to demonstrate a tether-assisted re-entry concept, whereby payload will be returned to Earth using momentum provided from a swinging tether. Deployment takes place in two phases: 1) deployment of 3.5 km of tether to the local vertical and hold, and 2) deployment to 30 km for a swinging cut. Optimal trajectories are determined for both phases after comparing the effect of different cost functions on the deployment dynamics. Closed-loop control is provided by linearising the dynamics around the optimal trajectories and solving a receding horizon control problem for a set of linear feedback gains. The controllers are tested in a flexible tether model with disturbances. A hardware-in-the-loop deployment test is used to validate the controller.
Drilling Processes Using Drag Bits and Its Application

This paper proposes an analytical model to describe rock drilling processes using drag bits and rotary drills, and to induce relations among rock properties, bit shapes, and drilling parameters (rotary speed, thrust, torque, and stroke). In this model, a drilling process is divided into successive cycles. Each cycle includes two motions: feed and cutting. According to this model, drilling torque includes four components generated from cutting, friction, feed, and idle running respectively, the first three items are all proportional to the UCS (uniaxial compressive strength) when the penetration rate is constant. Laboratory tests verified the correctness and effectiveness of the proposed model qualitatively. Especially, the influence of friction on the flank face and the idle running was confirmed. Field experiments were performed. The results showed good correlation between the torque, penetration rate, and UCS. The proposed model and equations engender the possibility of eliminating useless components of cutting forces when investigating the relation between mechanical data and physical properties of rocks.
Double gate MOSFET technology and applications

In this thesis, Double Gate (DG) MOSFET technology is studied and subsequently some useful applications are proposed based on the studies performed as described. When conventional MOSFET technology becomes harder and harder to scale down in size, DG MOSFET is believed to be a substitute as it can provide lower Threshold Voltage (VT) and higher on/off current ratio through gate coupling effect. A simple process for planar DG MOSFET with two separated gates is proposed and fabricated for study purpose. DG MOSFET properties are found when comparing with other Single Gate (SG) devices being fabricated together. As only self-aligned DG MOSFET will be attractive to industrial demand, a self-aligned DG MOSFET process is proposed and fabricated based on previous process fabrication experiences. To further increase the circuit density, a 3-D CMOS inverter, with DG PMOS sitting on top of SG NMOS, is also proposed and fabricated. A 60% area reduction is found when comparing it to the conventional CMOS inverter. As interconnect RC delay has become the major limitation in Integrated Circuit (IC) performance, 3-D ICs are so believed to be the future trend to reduce the interconnecting loading by allowing shorter connection path. A local-clustering technology is proposed based on the fabricated 3-D CMOS inverter. Simulation results show that significant reductions in interconnect loading; critical path delay and circuit area are achieved in local-clustering 3-D circuits without causing additional temperature rise. Conventional FLASH memory is difficult to scale down due to the conflicting requirements on gate oxide thickness from SCEs control and data retention respectively. An original Opposite Side Floating Gate (OSFG) FLASH memory is proposed based on the study of gate coupling effect through fabricated DG MOSFET devices. The operations of 50nm OSFG-FLASH cells, including reading, programming, erasing and disturbs, are discussed in detail and demonstrated through simulation.
Transient discrimination using a subspace method [acoustic array signal processing]

This paper describes a method using a subspace algorithm that can be used to discriminate between signals. Discrimination is necessary to ensure that the same transient from different data records is used in processing. The subspace discrimination algorithm was tested against synthetic transients and found to discriminate well at high signal-to-noise ratios (SNRs).

Umfang und Kompensation von Überstunden: eine vergleichende Analyse für Westdeutschland und Großbritannien

In the 1990s overtime incidence in Great Britain and West Germany is quite similar, while the average amount of hours of overtime for full-time male workers with overtime in Great Britain is roughly twice those in Germany for all years. We observe striking differences between the two countries with respect to overtime compensation patterns and their change over time. In Germany, we observe a remarkable decrease in the share of workers who work paid overtime and a significant increase in the share of workers with overtime compensated with extra days off later on, while in Great Britain shares of workers with paid or unpaid overtime are quite stable. Considering the relationship of straight-time working hours and the amount of overtime hours, we provide evidence for a strong negative relationship in Great Britain whereas in Germany the impact of straight-time working hours on overtime work is only weakly negative. Furthermore, we illustrate that a policy of reducing the amount of paid overtime would affect the monthly labor earnings distribution in Germany while we cannot detect any impact for Great Britain. Die Studie analysiert die Determinanten der Inzidenz, des Umfangs und der Kompensation von Uberstunden in Westdeutschland und Grosbritannien in den Jahren 1991 bis 1998. Istdie Inzidenz von Uberstunden in beiden Landern noch durchaus vergleichbar, so arbeiten britische Arbeitnehmer im Mittel doppelt so viel Uberstunden wie vergleichbare westdeutsche Arbeitnehmer. Hinsichtlich der Kompensation von Uberstunden zeigt sich, dass in Westdeutschland ein starker Ruckgang des Anteils der bezahlten Uberstunden an allen geleisteten Uberstunden im Zeitablauf zu beobachten ist, wahrend in Grosbritannien in den 90‘er Jahren die Abgeltungsmuster von Uberstunden weitgehend stabil waren. In Westdeutschland ist nur ein sehr schwacher negativer Zusammenhang von tariflich vereinbarter Arbeitszeit und geleistetem Uberstundenvolumen zu beobachten, wahrend in Grosbritannien eine signifikant negative Beziehung zwischen vereinbarter Wochenarbeitszeit und geleistetem Uberstundenvolumen besteht. Dieses Ergebnis legt nahe, dass gesetzliche oder tarifvertragliche Masnahmen zur Reduktion der vereinbarten wochentlichen Arbeitszeit in beiden Landern wohl kaum nennenswerte positive Beschaftigungseffekte zeitigen wurden. Eine Simulation der Verteilungseffekte eines vollstandigen Abbaus aller bezahlten Uberstunden fur das Jahr 1998 zeigt, dass in Westdeutschland hochqualifizierte Arbeiter und qualifizierte Angestellte Einkommenseinbusen hinnehmen mussten, wahrend dies in Grosbritannien keine nennenswerten Effekte hatte.
A New Efficient Cache Replacement Strategy for Named Data Networking

The Information-Centric Network (ICN) is a future internet architecture with efficient content retrieval and distribution. Named Data Networking (NDN) is one of the proposed architectures for ICN. NDN’s innetwork caching improves data availability, reduce retrieval delays, network load, alleviate producer load, and limit data traffic. Despite the existence of several caching decision algorithms, the fetching and distribution of contents with minimum resource utilization remains a great challenge. In this paper, we introduce a new cache replacement strategy called Enhanced Time and Frequency Cache Replacement strategy (ETFCR) where both cache hit frequency and cache retrieval time are used to select evicted data chunks. ETFCR adds time cycles between the last two requests to adjust data chunk’s popularity and cache hits. We conducted extensive simulations using the ccnSim simulator to evaluate the performance of ETFCR and compare it to that of some well-known cache replacement strategies. Simulations results show that ETFCR outperforms the other cache replacement strategies in terms of cache hit ratio, and lower content retrieval delay.

A Verifiable Ring Signature Scheme of Anonymous Signcryption Using ECC

: The ring signature does hide the member of actually signature in the all possible signer. This technique was introduced by Rivest, Tauman and Shamir in 2001. This paper presents elliptic curve cryptosystem using signcryption algorithm with the anonymity feature. In the present paper, combines ring signature scheme with signcryption method to produce the anonymity feature for the signcryption scheme and discuss the characteristic of the security. Because elliptic curve cryptosystem yields like as small bandwidth requirements, low computation load, and high security and methodology of ring signature gives without revealing the actual signer to all possible signers. Combining the benefits of these two methodology, the result is an efficient anonymous signcryption algorithm and highly secure.
Various aspects of sustainability analysis in Georgia

In 2001 the Georgia Traditional Industries Program (TIP) sponsored a cooperative study at the D.B. Warnell School of Forest Resources, University of Georgia, to analyze the long-term sustainability of the fiber supply in Georgia. The subject of this study is relevant to a diverse array of disciplines, and it offers the opportunity to explore various aspects of sustainability not directly related to the supply of fiber or timber alone. Examples of such aspects include studies of biomass densities and production, carbon densities, sequestration and credits, and landscape changes. We describe some of the technical aspects of data pooling and compilation, program settings and assumptions, and initial findings relating to this study.
Horizontal Semicircular Canal Orientation and the 3-D Vestibulo-Ocular Reflex

Goal. The three-dimensional vestibulo-ocular reflex (3-D VOR) is responsible for the maintenance of stable vision through generating compensatory eye movements in response to head movements. The main functional components of the 3-D VOR are the semicircular canals. The anatomy of the three canals is complicated, requiring the definition of several natural coordinate systems in order to assess the canals' functionality. Most notably, the horizontal canals form a significant angle (25°) with respect to the earth-horizontal (E-H) while the head is upright. The goal of this study was to determine the influence of head pitch orientation on the quality of the VOR, and thus to identify the 3-D VOR dependence on the canal anatomy and orientation. Methods. Eight healthy upright seated subjects underwent whole-body sinusoidal and transient stimulation delivered by a six degree of freedom (6-DOF) motion platform. Small-amplitude sinusoidal oscillation was delivered around the yaw axis and axes in the horizontal plane between roll and pitch at increments of 22.5°. Transients were delivered in yaw, roll and pitch and in the vertical canal planes. This sequence of stimuli was repeated for the subject with his/her head under three different initial positions: upright, pitched nose down 16°and 25°, aligning the horizontal canal prime direction and maximum response direction with the E-H, respectively. 3-D scleral search coils were used for the recording of eye movements. Results. For sinusoidal stimulation around axes in the horizontal plane, a decline in gain and an increase in misalignment were found for increasing downward head pitch, in the light as well as in darkness. All component gains had lower values in darkness than in light. For vertical axis rotation, this decrease in gain and increase in misalignment was also present, except for the torsion component which increased with both upward and downward (from upright) pitch. Transient stimulation yielded overall lower gains than sinusoidal stimulation. No significant differences between the different head pitch orientations were found for vertical axis stimulation. For transients around axes in the horizontal plane however, the horizontal component gain increased with increasing nose-down pitch, while overall the vertical component decreased. Conclusions. The incongruence between the mathematically modelled coordinate systems of the semicircular canals and the obtained results in terms of gain and misalignment, suggests the contribution of other mechanisms to the 3-D VOR. The gravity-induced otolith-mediated VOR is likely to have an additional effect with the head pitched. The inhibitory effect of the otolith-mediated gravity vector on the torsional eye position is a possible explanation for the reduction in gain for sinusoidal rotation around axes in the horizontal plane. The opposite is seen during transient stimulation, which could be attributed to the otolith organs' low-pass behaviour.
