Partial sensing is used to reduce the power consumption of pedestrian user equipment (P-UE) that operates in the signal environment of a mode-2 sidelink. However, because the data trans-mission is allowed only for the window duration of each corresponding P-UE, the throughput of the P-UE decreases by the ratio between the width of the window and the entire data period. This paper presents a novel method for enhancing the throughput of the P-UE that operates with partial sensing in the mode-2 sidelink. The proposed technique employs an additional UE, denoted the roadside unit (RSU), to collect the sensing results from each P-UE that operates with partial sensing. The proposed RSU sequentially aligns all of the partial sensing windows, such that the combination of each partial sensing window can eventually provide an almost complete sensing result. In this study, extensive computer simulations were performed. The results reveal that the proposed method enhances the throughput of each P-UE operating with partial sensing almost to that of full sensing without increasing the required power consumption.

In scientific computing, the acceleration of atomistic computer simulations by means of custom hardware is finding ever-growing application. A major limitation, however, is that the high efficiency in terms of performance and low power consumption entails the massive usage of low precision computing units. Here, based on the approximate computing paradigm, we present an algorithmic method to compensate for numerical inaccuracies due to low accuracy arithmetic operations rigorously, yet still obtaining exact expectation values using a properly modified Langevin-type equation.

Dynamic Resource

Efficient resource utilization plays a vital role in cloud computing since the shared computational power of the resources is offered on demand. During dynamic resource allocation sometimes a server may be over utilized or underutilized thus leading to excess of energy consumption in the data centers. So the proposed system calculates the over utilization and underutilization of a CPU and RAM usage and also considers the network bandwidth usage to reduce power consumption in the cloud data center. Hence, a novel method is used for minimizing power consumption in the data center

This paper proposes a novel method to on-machine determine the three error components of a precision linear slide: the straightness motion, the yaw and the roll under the effect of thermal distortion caused by friction and drive. The Integrated Sensing System (ISS) is then introduced for implementing this novel method on an illustrative model of a linear slide. The error separation algorithm used in the system is based on the Fourier Eight Sensor (F8S) method. The theory and procedures are presented, and computer results are analyzed. The effectiveness of the novel method is validated through computer simulations.

Domino Circuits

This paper proposes a novel method to control leakage and noise in domino circuits for wide fan-in OR logic with low power consumption, low process variation, and higher noise margin under the similar delay condition. In the proposed method, output and dynamic nodes are isolated from the PDN (Pull-Down Network) to improve the noise immunity and reduce switching activity. Further, with the aid of a transistor in the stack, the sub-threshold current is reduced. Thus, the proposed domino is applicable for high-speed and low-power applications in deep sub-micro-range. Simulation results show that the proposed domino improves the noise immunity and figure of merit (FOM) by factors of 1.95 and 2.34, respectively, with respect to the conventional domino with a footer. Along with this improvement, 26% reduction is also observed in power consumption. The entire simulations for all the domino circuits are done at 45-nm CMOS technology by using SPECTRE simulator under the Cadence Virtuoso environment.

Repetition Interval

In the modern wars under the condition of informationalization, radar signals are generally characterized by repetitive patterns in time, so it is one important task of Radar Warning Receiver (RWR) to estimate the Pulse Repetition Interval (PRI) of all radar signals by intercepting and identifying the mixed radar signals. Because each transmitted radar signal are arbitrary in general. From the view of statistic, the transmitted radar pulse train from different radars is mutual independent. So the constituted model of RWR and radar transmitters accord with blind source separation which can separate mixed signals into pure signals. A deinterleaving method using blind source separation for estimating the PRI of each radar signals is proposed. The implementation architecture of the proposed method is given. Finally, computer simulations show the proposed method can gain good performance for the estimation of PRI of radar signals.
