Thermo-Mechanical Analysis of Water-Cooled Gun Barrel During Burst Firing

The thermo-mechanical stress and deformation of water-cooled gun barrel during burst firing are studied by finite element analysis （FEA）. The problem is modeled in two steps： 1） A transient heat transfer analysis is first carried out in order to determine temperature evolution and to predict the residual temperatures during the burst firing event; 2） The thermo-mecha-nical stresses and deformation caused by both the residual temperature field and the gas pressure are then calculated. The results show that the residual temperature field tends to a steady state with the increasing of rounds. The residual temperature field has much effect on the gun barrel stress and deformation, especially on the assembly area between barrel and water jacket. The gage between the barrel and water jacket is the critical factor to the thermo- mechanical stress and deformation. The results of this analysis will be very useful to develop the new strength design theory of the liquid-cooled gun barrel.     

Turbo-DFH Coding and Iterative Decoding

We combine the Turbo codes with differential frequency hopping （DFH） technique and propose a new technique called Turbo-DFH coding. The structures of Turbo-DFH encoder and decoder are given. Taking aim at characteristic of Turbo-DFH system, the modified Log-MAP algorithm is presented and used for iterative decoding of Turbo-DFH decoder. Simulation results show that because the ideas of random coding and iterative decoding are used, the bit error rate （BER） performance of the Turbo-DFH system is better than that of the conventional DFH system.     

The Eleventh Hour.

Discusses the efforts of the APA Central Office to correct the image of psychology on the network television show The Eleventh Hour. The author objects to APA's policing the image of psychology in entertainment media (not news, nonfiction features, or documentaries).

A true life drama--The case of Anonymous versus NBC.

Discusses the development of The Eleventh Hour, an NBC network television show prominently featuring psychiatrist and psychologist characters. The author reproduces several documents showing the position of the American Psychological Association about the show, and the efforts of the APA to correct errors presented in the show's depiction of psychology, psychiatry, and the care of mentally ill patients.

P-μc-Si1-xGex:H thin film by VHF-PECVD

In this paper,a series of boron doped microcrystalline hydrogenated silicon-germanium(p-μc-Si1-xGex:H)was deposited by very high frequency plasma-enhanced chemical vapor deposition(VHF-PECVD)from SiH4 and GeF4 mixtures.The effect of GeF4concentration on films'composition.structure and electrical properties was studied.The resuIts show tllat with the increase of GeF4 concentration,the Ge fraction x increases.The dark conductivity and crystalline volume fraction increase first,and then decrease.When the GC is 4%,p-μc-Si1-xGex:H matefiai with high conductivity,low activation energy(σ=1.68 S/cm,Eg=0.047 eV),high crystalline volume fraction (60%)and with an average transmission coefficient over the long wave region reaching 0.9 at the thickness of 72 am was achieved.The experimental results were discussed in detail.

OPTIMAL SYNTHESIS OF PLANAR 4 LIMBS 3-DOF OVERACTUATED PARALLEL MECHANISMS

Optimal synthesis of a 3-DOF 4 limbs planar parallel mechanism with actuated redundancy is studied. The kinematics equation of the mechanism is developed and the topology of the mecha-nism is classified. The kinematics and force properties of the mechanisms according to the topologies are compared. Furthermore, a global optimizing formulation is derived from the condition number that is a local index usually used to scaling the manipulability isotropy quantitatively. The optimiza-tion is solved by genetic algorithm. The numerical results show that the topology of the mechanisms can influence the kinematics and force property considerably, and the manipulation dexterity of the mechanisms can be improved distinctly by the given formulations and the suggested optimization algorithm.

Wearable Technologies,Portable Architectures and the Vicissitudes of the Space Between

The omnipresence of the iPod and mobile phone has ensured portable and wearable technologies' highly privileged position in contemporary society. They are at the top of the pile where conspicuous consumption is concerned - you only have to visit an Apple store on a Saturday afternoon to witness the degree to which this highly sought-after gadgetry has become subject to consumer frenzy and speculation. Here, Despina Papadopoulos reviews the particular social and cultural impact of wearable devices. She also welcomes in a new generation of interactive designers who are investigating the human and emotional potential of emergent technologies. Copyright © 2007 John Wiley & Sons, Ltd.
