Lab-on-CMOS chips (LOCMOS) are sophisticated miniaturized analysis tools based on integrated circuit (IC) microchips performing various laboratory functions. We have developed a low temperature co-fired ceramic (LTCC) package for a LOCMOS application regarding cytotoxicity assessment of nanomaterials. The LTCC packaged capacitance sensor chip is designed for long-term cell viability monitoring during nanoparticle exposure. The introduced LTCC package utilizes the flip chip bonding technique, and it is biocompatible as well as able to withstand the environmental conditions required to maintain mammalian cell culture directly on the surface of a complementary metal oxide semiconductor (CMOS) integrated circuit.

${\hbox {Q}}$ Factor Analysis of Reflectarray Elements Investigating the Effects From Angle of Incidence Using Floquet Modes

引用

IEEE Transactions on Antennas and Propagation 2014年第10期62卷 5017-5028页

作者： Kalyan K. Karnati Yazid Yusuf Siamak Ebadi Xun Gong Department of Electrical Engineering and Computer Science Antenna RF and Microwave Integrated (ARMI) System Laboratory Orlando FL USA TriQuint Semiconductor Inc Apopka FL USA Intellectual Ventures Bellevue Washington USA

A theoretical approach to investigate the effects of incidence angle on reflection properties of reflectarray elements is developed for the first time. Utilizing coupled-mode theory and Floquet analysis, the dependence of reflection coefficient on incidence angles and plane of incidence is presented in terms of Q factors. A unit cell excited by a plane wave at different incidence angles is shown to have varying coupling conditions and reflection properties. Emphasis is laid on elements located on planes where extremities in performance tend to occur. Anomalous phase characteristics are observed for particular polarization and incidence angles. The antenna element properties are assessed in terms of maximum reflection loss and slope of the reflection phase. A thorough analysis is performed at K a band and the results obtained are verified using full-wave simulations. Reflection coefficients over a 749-element reflectarray aperture for a broadside radiation pattern are presented for a couple of cases and the effects of coupling conditions in conjunction with incidence angles are demonstrated. The presented theory provides explicit physical intuition and guidelines for efficient and accurate reflectarray design.

The 4-Wheel Skid-Steering Mobile Manipulators (4W-SSMM) have been widely used in many complex task environments, in which, it often encounter all sorts of complicated driving conditions. In these situations, excessive slipping would be likely to happen, and the robot's tracking stability cannot be assured. In order to solve this problem, a stability control scheme which is based on the slip ratio and an active mechanical arm is proposed in this paper. In this scheme, the load of tire can be changed by changing the motion attitude of the manipulator, the excessive slip can be avoided and the tracking stability of 4W-SSMM can be assured. The dynamic model of it is derived in this paper. The results of the experiment and simulation show that, the model constructed in this paper can reflect the relationship between the motion attitude of the manipulator and the load of tire accurately, and the scheme proposed in this paper is feasible and effective.

The 3 rd Generation Partnership Project - Long Term Evolution (3GPP-LTE) is the best choice for multimedia data transmission in demanding situation. The 3GPP LTE provides high data transmission rate between the User Equipment (UE) and Evolved Node B (eNB) with lower latency and better throughput. However, with the advancement and increasing traffic of data load, it is necessary to have data scheduling with user requests. In real life situations, mobile users become impatient when they don't receive their desired data. Moreover, the LTE Enhanced Multimedia Broadcast Multicast Services (eMBMS) does not provide any type of scheduling to measure and manage the impatient user request in multimedia broadcasting scenario. So, we consider this situation in our proposed scheme and simulated a new type of hybrid scheduling scheme to overcome this problem. It also takes care of the server anomalies arising from multiple requests sent by the same user for the same data.

Video caching in Radio Access Network: Impact on delay and capacity

IEEE Conference on Wireless Communications and Networking

作者： Hasti Ahlehagh Sujit Dey Mobile System Design Laboratory Department of Electrical and Computer Engineering University of California San Diego USA

In this paper, we introduce distributed caching of videos at the base-stations of the Radio Access Network (RAN) as a way to reduce the need to bring requested videos from Internet CDNs, thereby reducing backhaul transmission, improving video quality of experience - delay and video stalling - and increasing overall network capacity to support more number of simultaneous video requests. Unlike Internet CDNs that can store millions of videos in a relatively few large sized caches, our proposed caching architecture consists of a very large number of micro-caches, with each base-station micro-cache being able to store only 1000s of videos, and hence may not be able to have high cache hit ratio. To address this challenge, we propose two new caching policies based on the User Preference Profile (UPP) of users in a cell: R-UPP (Reactive UPP) and P-UPP (Proactive UPP). Further, for videos that result in cache misses and need to be fetched from Internet CDNs, we develop a video scheduling approach that allocates the RAN backhaul resources to the video requests so as to reduce video latency and increase network capacity. We develop a discrete event statistical simulation framework using MATLAB to study the performance of RAN caching. Our simulation results show that RAN micro-caches with the proposed UPP-based caching policies, together with the proposed scheduling approach, can improve the probability of video requests that can meet initial delay requirements by almost 60%, and the number of concurrent video requests that can be served by up to 100%. The results also show that UPP based policies can enhance network capacity by up to 30% compared to conventional caching policies.

Impact of the quality of spatial 3D city models on sensor networks placement optimization

引用

Geomatica 2012年第4期66卷 291-305页

作者： Argany, Meysam Mostafavi, Mir Abolfazl Akbarzadeh, Vahab Gagné, Christian Yaagoubi, Reda Centre for Research in Geomatics Department of Geomatics Université Laval QC Canada Computer Vision and System Laboratory Department of Electrical Engineering and Computer Engineering Université Laval QC Canada Department of Geomatics Faculty of Environmental Design King Abdulaziz University Jeddah Saudi Arabia

Sensor networks are increasingly used for tracking, monitoring, and observing spatial dynamic phenomena in the real world (e.g. urban area). In order to ensure an efficient deployment of a sensor network, several optimization algorithms have been proposed in recent years. Most of these algorithms often rely on oversimplified sensor models. In addition, they do not consider information on the terrain topography, city models, and the presence of diverse obstacles in the sensing area (e.g. buildings, trees, poles). Only some of those optimization algorithms attempt to consider the terrain information in the optimization of a sensor network deployment. However, most of these algorithms consider that the spatial models used for this purpose are perfect representations of the reality and are not sensitive to the quality of the information. However, spatial models are simplified representations of a complex reality, and hence are inherently uncertain. In this paper we will investigate the impact of the spatial data quality on the optimization of a sensor network and its spatial coverage in an urban area. For this purpose, we will investigate specific implications of spatial data quality criteria for a 3D city model that will be used in sensor network optimization algorithms. Then, we will analyze the impact of some of those criteria on the estimation of sensor network coverage.!Afterwards, a case study for sensor network deployment in an urban area will be presented. This case study will demonstrate the impact of 3D city models quality on the estimation of coverage using global and local optimization algorithms. Finally, the results obtained from this experimentation will be presented and discussed.
