This paper proposes “MobileSocket” which realizes session layer communication continuity support for Java Applications towards the continuous operations for mobile applications. In the mobile computing environment where mobile hosts moves around the network even during applications are communicating with the remote, maintenance of the communication continuity between the applications is signifi...

One of the most promising applications of cognitive radio networks (CRNs)is the efficient exploitation of TV white spaces (TVWSs) for enhancing the performance of wireless networks. In this paper, we propose a cross-layer design (CLD) of carrier sense multiple access with collision avoidance (CSMA/CA) mechanism at the medium access control (MAC) layer with spectrum sensing (SpSe) at the physica...

It becomes complicated to represent complex object structures as a network of nodes and arcs when a large volume of objects is to be browsed. This paper presents the issues of designing and implementing an icon-based graphic user interface for representing complex relationship instances as a node-and-link form. The iconbased browser presented in this paper supports the simplification of the vis...

For n-type solar cell concepts, B emitters are commonly diffused in a BBr3-based process. However, the metallization of these p layers is challenging. Up to now, low contact resistances on B emitters were only reported to be possible using Al-containing Ag screen-printing pastes. A drawback of the addition of Al to the paste is that, facilitated by the Al, deep metal spikes grow into the Si sur...

(This is part 2, continued from “Use of harsh Wafer Probing to Evaluate Traditional Bond Pad Structures”). Goals for circuit under pad (CUP) in aluminum – silicon dioxide (Al – SiO2) based IC pad structures include the design of metal interconnects in all layers beneath the pad Al, and the ability to withstand harsh probing and wirebonding stress without SiO2 cracking, without deforming or bend...

Photodiodes have found wide practical applications as sensing and information transmission technology in different environments. Viktor Brus co-workers (article number 2202028) report a novel high-performance UV-vis-NIR heterojunction photodiode based on radiation-resistant functional semiconductor materials: TiN ‘window’ layer CdZnTe photoactive layer. This work pushes the current detectivity–...

The performance of the Cu2ZnSnS4 based solar cell is investigated using a simulation program called Solar Cell Capacitance Simulator (SCAPS). The cell structure is based on Cu2ZnSnS4 (CZTS) compound semiconductor as the absorber layer, n-doped and un-doped (i) zinc oxide as the window layer, In2S3 as the buffer layer. We study the influence of the defect density, carrier density, thickness of t...

Low-temperature epitaxial growth of AlN ultrathin films was realized by atomic layer deposition (ALD) together with the layer-by-layer, in-situ atomic layer annealing (ALA), instead of a high growth temperature which is needed in conventional epitaxial growth techniques. By applying the ALA with the Ar plasma treatment in each ALD cycle, the AlN thin film was converted dramatically from the amo...

The initial KATRIN Detector prototype is a Hamamatsu S3204-09 window-less Si PIN photodiode. The KATRIN experiment is designed to analyze tritium beta decay and, from that analysis, measure the mass of the neutrino with an upper limit of 0.2 eV. To achieve this sensitivity the background must be extremely low and noise reduction is imperative. Determining the dead layer of the prototype detecto...

In this paper, we propose a two-layer model for TCP traffic with burstiness effect. We show that the backlog in bottleneck queue is bounded by the sum of two components: the long term effect of congestion window control algorithm and the short term effect of burstiness. This motivates a formal definition of burstiness. A simple algorithm is proposed to measure and control burstiness at the send...
