VLSI systems in the nanometer regime suffer from high defect rates and large parametric variations that lead to yield loss as well as reduced reliability of operation. In this paper, we propose a novel memory-based computation framework that exploits on-chip memory for reliable operation by transferring activity from a defective or unreliable functional unit to the embedded memory. This allows the...
The physical concepts developed to describe the transient activation of boron during post-implantation annealing are based on the concurrent formation of complexes comprising boron atoms and self-interstitials. A complete implementation into TCAD software leads to a high number of equations to be solved which is often inadmissible for multi-dimensional simulations. In this work, a minimum number of...
The prerequisites of success and reasons for failure for enterprise integration projects are still not well-understood as evidenced by large failure rates, including cost or schedule overruns, abandoned projects, and projects delivered with diminished functionality. These failures point to the inherently human activities of planning and overseeing that are critical to successful large-scale integration...
High defect rate in emerging nano-devices mandates new computational models that can tolerate defects thereby rendering reliability of operation and reasonable manufacturing yield. In a bottom-up system design approach using nano-crossbar applications are typically mapped into a crossbar using either PLA or lookup table (LUT) implementation of a logic circuits. LUT-based implementation has some definite...
In 802.11 wireless links with disabled MAC retries, data and ACK packets within a TCP session collide resulting in packet losses. We show in this paper that in this situation, certain popular optimizations of TCP (fast-recovery) worsen the performance by causing deadlocks that terminate with timeouts. We compare the performance of optimized TCP versions (Reno and NewReno) with an earlier version of...
The diffusion length of the flash anneal is lowest for all different implant conditions. For the arsenic implant similar diffusion length is seen for all the processes that include a spike anneal due to the fact that the overall thermal budget is mainly determined by the spike anneal. Boron implants into crystalline as well as pre-amorphized silicon show similarly low sheet resistance independent...
Scan-based DFT enhances the testability of a system by making its internal nodes more observable and controllable. However, in case of a secure chip, scan chain increases its vulnerability to attack, where the attacker can extract secret information by scanning out states of internal nodes. This paper presents VIm-Scan: a low overhead scan design methodology that maintains all the advantages of a...
A data acquisition system based on sampling analog to digital converters (ADCs) and data processing in field programmable gate arrays (FPGAs) is presented. Up to 32 ADC channels are combined with reconflgurable logic on a small mezzanine form factor card to get a handy module for analog data acquisition. This module can then be mounted either on a dedicated detector frontend or included in an Advanced...

Ensuring reliability of operations under increasing temperature and process variations has emerged as a major design concern at nanometer scale. Adaptive systems that can dynamically change its operating conditions (voltage, frequency etc.) to accommodate for temperature and process variation has emerged as a promising solution. Such a system, however, requires efficient design techniques that can...
Cache and forward (CNF) Architecture is a novel architecture aimed at delivering content efficiently to potentially large number of intermittently connected mobile hosts. It uses a reliable hop-by-hop transport mechanism where in-network storage is leveraged to store the entire file in each node, before forwarding it towards the destination(s). Links between nodes may be wired, or wireless, 802.11...
Sensor fusion is a widely used strategy where the system-variables are unobservable. In this work a (back-propagation neural network) BPNN based sensor fusion model has been developed for tool-condition-monitoring (TCM) in flexible manufacturing applications (as a case study) and different performance improvement strategies have been incorporated with notes on generalized applicability to other sensor...
TCP is mostly used protocol for data transmission over a network. There are some other transport layer protocols such as DCC, SCTP, RTP, IL, UDP, RUDP etc but TCP is well-known and most reliable for data transmission. The authors have also studied satellite link characteristics and found most error occurs in wireless medium for long delay path. We also analyze most recent algorithms and proposals...
The paper introduces a new interconnection system OMTSE (Optical Multi-Trees with shuffle Exchange) using both electronics and optical links among processors. The network has a total of N = 3n3/2 nodes. The diameter of the network is 0(log n) and the bisection width is 0(n3).
Although online learning is shifting the teaching paradigm at tertiary institutions, there are limited studies that assess the effectiveness of online courses, particularly in the occupational and environmental health field and among mature aged students. The main aim of this study was to evaluate the effectiveness of online i Blackboard! units as compared to traditional i paper basedi units taught...
In this paper we propose cmpTCP-Westwood (cmpTCPW), which is an extension of a variant of TCP-Westwood and SCTP. The proposed cmpTCPW has been implemented by altering and extending library-based open-source implementation of SCTP. The proposed cmpTCPW manages transmission control parameters of all paths simultaneously; a scheduler concurrently dispatches packets over all the paths from a common transmission...
Millisecond annealing either by flash lamp or laser appears to be the leading approach to meet the needs of ultra-shallow junction annealing and polysilicon activation for advanced technology nodes. There are many advantages to this technology including high electrical activation, excellent lateral abruptness, controlled and limited dopant diffusion and the ability to engineer the extended defects...
Formal specification, verification, modeling of distributed software systems including middleware is an important area of research [4], [5], [6], [8]. Even then, as of now, no universally accepted standard method for formalization of middleware exists. Mobile middleware systems are increasingly gaining importance due to cheap and highly efficient mobile computing and networking hardware, and also...
In this paper, we present a method for single channel noise reduction of heart sound recordings. Multiple noise sources, such as lung sounds, muscle contraction, and background noise can contaminate the heart sound collection making subsequent analysis difficult. Our approach is based on a spectral domain Minimum-Mean Squared Error (MMSE) Estimation, originally introduced by Ephraim and Malah in the...
