Mastcam image enhancement using estimated point spread functions 使用估计点扩展函数的Mastcam图像增强
C. Kwan, Minh Dao, Bryan Chou, L. Kwan, B. Ayhan
This paper summarizes some preliminary results in enhancing the spatial resolution of the left Mastcam images of the Mars Science Laboratory (MSL) onboard the Mars rover Curiosity. There are two multispectral Mastcam imagers, having 9 bands in each. The left imager has wide field of view, but low resolution whereas the right imager is just the opposite. Our goal is to investigate whether we can use the right Mastcam images to enhance the left Mastcam images. We first estimate the point spread function (PSF) between a pair of left and right Mastcam images using a sparsity based approach. We then apply the estimated PSF to enhance the other left images. Actual Mastcam images were used in our experiments. Preliminary results indicated that the image enhancement performance is mixed. That is, we can achieve good results in some left images and poor results in others. The mixed results point to a new direction for a future study, which involves the use of deep learning based on convolutional neural network (CNN) for PSF estimation and robust deblurring.
本文总结了“好奇号”火星探测器火星科学实验室(MSL)左侧桅杆摄像头图像空间分辨率提高的一些初步成果。有两个多光谱Mastcam成像仪,每个有9个波段。左边的成像仪视野宽,但分辨率低,而右边的成像仪正好相反。我们的目标是研究是否可以使用右侧的Mastcam图像来增强左侧的Mastcam图像。我们首先使用基于稀疏度的方法估计一对左右Mastcam图像之间的点扩散函数(PSF)。然后,我们应用估计的PSF来增强其他左侧图像。我们的实验使用了真实的Mastcam图像。初步结果表明,图像增强效果参差不齐。也就是说,我们可以在一些左图像中获得好的结果,而在另一些左图像中获得不好的结果。混合结果指出了未来研究的新方向,该研究涉及使用基于卷积神经网络(CNN)的深度学习进行PSF估计和鲁棒去模糊。

Framework for generating and designing spectrum awareness modules for opportunistic networking 为机会网络生成和设计频谱感知模块的框架
Oladiran G. Olaleye, Alaa Ali, Ahmed Aly, M. Iqbal, D. Perkins, M. Bayoumi
For improved spectrum utilization in opportunistic network (OppN), spectrum awareness (SA) metrics can be generated from the synthesis and analysis of both static and dynamic network parameters. However, there are several techniques and algorithms for evaluating network parameters. Hence, a standardized framework is needed for generating SA towards improved spectrum consumption. To the best of our knowledge, no such framework currently exist in literature. In this work, therefore, we propose a novel approach for constructing, justifying and improving SA modules for OppN. Our approach maps different SA metrics to network parameters, which we define as SA integrals. We derive the constant of proportionality (SA constant) between the metrics and the integrals as a function of reliability, computational complexity and latency. The derived SA constants can be used to justify and compare SA techniques and algorithms. Based on the results obtained from the modeling and simulation of an adhoc cognitive radio network, using QualNet, we illustrate the applicability of SA constant as an index (0.0 < SA constant < 1.0) for quantifying the level of SA derivable from any specified SA module.
为了提高机会网络(OppN)的频谱利用率,可以通过综合和分析静态和动态网络参数来生成频谱感知(SA)指标。然而,有几种评估网络参数的技术和算法。因此,需要一个标准化的框架来生成SA以改善频谱消耗。据我们所知,目前文献中还没有这样的框架。因此,在这项工作中,我们提出了一种新的方法来构建、验证和改进OppN的SA模块。我们的方法将不同的SA度量映射到网络参数,我们将其定义为SA积分。我们推导了度量和积分之间的比例常数(SA常数)作为可靠性,计算复杂性和延迟的函数。派生的SA常数可用于证明和比较SA技术和算法。基于对一个自组织认知无线电网络的建模和仿真结果,我们利用QualNet说明了SA常数作为一个指标(0.0 < SA常数< 1.0)的适用性,该指标用于量化任意指定的SA模块可衍生的SA水平。

KeyStroke logs: Are strong passwords enough? 击键日志:强密码足够吗?
Darshanie Sukhram, T. Hayajneh
As hackers develop sophisticated phishing and social engineering attacks, it is recommended that users be aware of common tactics and implement stronger and unique passwords for sensitive accounts. Malware typically involved in cyber-attacks includes viruses and worms. Keyloggers are designed to track and capture keystrokes made on devices. They are not given the same priority as the other types of malware, but are also considered malicious as it poses the same level of risk. Having a strong password in this instance does not provide a high level of protection as keyloggers will log each key typed. This paper will discuss the characteristics of keylogging software while providing a summary on methods of protection. Three keylogging software are tested against two anti-keylogging programs to identify what information is captured and which method of protection is stronger. A discussion on risk assessment with regards to keyloggers and remediation techniques is also included.
由于黑客开发了复杂的网络钓鱼和社会工程攻击,建议用户了解常见的策略,并为敏感帐户使用更强且唯一的密码。通常涉及网络攻击的恶意软件包括病毒和蠕虫。键盘记录器旨在跟踪和捕获设备上的按键。它们与其他类型的恶意软件没有相同的优先级,但也被认为是恶意的,因为它构成了相同级别的风险。在这种情况下使用强密码并不能提供高水平的保护,因为键盘记录程序将记录键入的每个密钥。本文将讨论键盘记录软件的特点,同时对保护方法进行总结。三种键盘记录软件针对两种反键盘记录程序进行测试,以确定捕获的信息和哪种保护方法更强。还包括对键盘记录程序和补救技术的风险评估的讨论。

Dynamic Fractional Frequency Reuse (FFR) scheme for two-tier network in LTE LTE两层网络的动态分数频率复用(FFR)方案
S. Alotaibi, R. Akl
Femtocell networks are a promising solution to enhance the capacity of the LTE networks, especially for the indoor environments. However, unplanned deployment of the femtocells causes the co-tier interference and cross-tier interference. The interference limits the advantages of deploying the femtocell networks. The Fractional Frequency Reuse (FFR) concept is introduced to mitigate the effect of the interference on the system. In this work, Dynamic scheme is proposed to partition the spectrum efficiently. The objective of the proposed scheme is to increase the capacity of the femtocells, which enhances the performance of the system and benefits of fmetocells. The proposed scheme assign less resources for macrocell's part, which has more deployed femtocells in order to reuse as much as possible of the available resources. An experiment is conducted in order to evaluate the proposed scheme. The results indicates that the proposed scheme can increase the capacity of the system.
Femtocell网络是一种很有前途的解决方案,可以增强LTE网络的容量,特别是在室内环境中。但是,飞基站的非计划部署会导致共层干扰和跨层干扰。干扰限制了部署飞蜂窝网络的优势。为了减轻干扰对系统的影响,引入了分数频率复用(FFR)概念。在这项工作中,提出了动态分割频谱的方法。该方案的目标是增加飞基站的容量,从而提高系统的性能和效益。该方案为macrocell部分分配较少的资源,使其具有更多的部署飞蜂窝,以尽可能多地重用可用资源。通过实验对所提出的方案进行了验证。结果表明,该方案能够提高系统的容量。

LTE fallback optimization using decision tree 基于决策树的LTE回退优化
Hussein Al Dorai, Luay Ali Al Irkhis
The voice call performance is still a challenge in the current 4G networks, providing the most perfect reliability and accessibility of the voice call is the target that all networks are looking for. Most of the networks have 3G layer that is sorted as backup layer for 4G layer, because 4G layer has less coverage which comes as consequence of mainly two reasons: First reason is the 4G frequency is high in order to have greater bandwidth; second reason is the delay of the sites' civil deployment. 5G networks will add more aggressive effects to these two reasons, such as some operators plan to jump directly from 3G to 5G which means more challenges because 5G needs more bandwidth to achieve super performance that can be done only on very high frequencies which have a small footprint. That means the operators are still in need of 3G. This paper develops a new voice call scenario for 4G layer to fallback. The new scenario will shorten the time of mobile-to-mobile setup time which is one of the main keys that operators compete with each other. The call performance will be found in advance to be a condition in order to roll over the new scenario, and that is optimized and based on individual call process by using the decision tree to have optimal decision.
在当前的4G网络中,语音通话性能仍然是一个挑战,提供最完美的语音通话可靠性和可访问性是所有网络都在追求的目标。大多数网络都有3G层作为4G层的备份层,因为4G层的覆盖范围较小,主要有两个原因:一是4G频率高,以便有更大的带宽;第二个原因是民用部署的延迟。5G网络将给这两个原因带来更积极的影响,比如一些运营商计划直接从3G跳到5G,这意味着更多的挑战,因为5G需要更多的带宽来实现超级性能,而这只能在占用空间很小的非常高的频率上实现。这意味着运营商仍然需要3G。本文提出了一种新的4G层回退语音呼叫场景。新的方案将缩短移动到移动的设置时间,这是运营商相互竞争的主要关键之一。呼叫性能将被预先发现为滚动新场景的条件,并通过使用决策树对其进行优化,并基于单个呼叫过程进行优化以获得最优决策。

Enhanced load balancer with multi-layer processing architecture for heavy load over cloud network 增强的负载平衡器,具有多层处理架构,适用于云网络上的高负载
N. S. Randhawa, Mandeep K. Dhami, Parminder Singh
Load balancing is an efficient part of cloud computing environment which confirms that all procedures work similar amount of work in particular time period. The different types of algorithms for load balancing over cloud environment have been implemented with the main goal to develop cloud resources accessible to the end users with easy and accessibility. The main load balancing problem is the run time overload owed to the change of load data amongst CPUs, selection of processes for decision making and transfers the job from processor to processor. The proposed approach analyzes the conditions and divides the load balancing approach in multiple layers. The Multi-queue management policy is used to check and divide requests in multiple queues according to their execution priorities and other layer handles inner requests of the queue over cloud network using network manager. Due to handling of both phases of this area the problem of heavy load processing overcome in various terms like energy consumption, response time, network load. All these terms used to analysis the performance of a system along with heavy load on network. The proposed metrics calculated in .net platform and it achieves the overall 28% approximate enhancement in all the cases.
负载平衡是云计算环境的一个有效组成部分,它确认所有过程在特定时间段内完成的工作量相似。在云环境中实现不同类型的负载平衡算法的主要目标是开发最终用户可以轻松访问的云资源。主要的负载平衡问题是由于cpu之间负载数据的变化、决策过程的选择以及任务从处理器到处理器的传输而导致的运行时过载。该方法通过对条件的分析,将负载均衡方法划分为多个层次。多队列管理策略用于根据请求的执行优先级在多个队列中检查和划分请求,其他层使用网络管理器在云网络上处理队列的内部请求。由于处理了该区域的两个阶段,因此在能耗、响应时间、网络负载等各个方面克服了重载处理的问题。所有这些术语都用于分析系统在网络负载较大时的性能。所提出的指标在。net平台上进行了计算,在所有情况下都实现了28%左右的总体增强。

Multi-modal data fusion of Voice and EMG data for robotic control 机器人控制中语音和肌电数据的多模态融合
Tauheed Khan Mohd, Jackson Carvalho, A. Javaid
Wearable electronic equipment is constantly evolving and is increasing the integration of humans with technology. Available in various forms, these flexible and bendable devices sense and can measure the physiological and muscular changes in the human body and may use those signals to machine control. The MYO gesture band, one such device, captures Electromyography data (EMG) using myoelectric signals and translates them to be used as input signals through some predefined gestures. Use of this device in a multi-modal environment will not only increase the possible types of work that can be accomplished with the help of such device, but it will also help in improving the accuracy of the tasks performed. This paper addresses the fusion of input modalities such as speech and myoelectric signals captured through a microphone and MYO band, respectively, to control a robotic arm. Experimental results obtained as well as their accuracies for performance analysis are also presented.

Investigation of IGBT behavior in DC systems with advanced circuit breaker technology 采用先进断路器技术的直流系统IGBT行为研究
I. Almutairy, J. Asumadu, Marwan Alluhaidan
Certain advancements have been ongoing in power electronics, DC transmission is looking more advantageous than it ever has. Since the application of power converters and advanced circuit breaker technology, distribution, and transmission of DC energy has become increasingly dependable. Some of the motives for the tendency to select direct current circuit breakers (DCCB) for distributed power systems are clear, while some of the other reasons are not so apparent. The purpose of this paper is to communicate the findings of an investigation into basic IGBT switching behavior and the purpose for the choosing of these DC SSCBs for distributed power systems over the standard systems and devices already in place. Here, some General information about circuit breakers is provided. The two main types of circuit breakers for DC systems are discussed, though there are some other types that exist, we focus on these two types, electromechanical and solid state with preference given to the solid state. The advantages of Solid State circuit breakers are discussed. A mathematical model of IGBT has been conducted and discussed. The last thing outlined in the paper is a section about simulation results and analysis of the IGBT.

No inter-network tracking area update scenario toward 5G network 无面向5G网络的网间跟踪区域更新场景
Hussein Al Dorai, Luay Ali Al Irkhis
The 5G network becomes a new layer above the existed 4G, 3G, and 2G networks. Developing a 5G network has a lot of challenges. The main challenge is the coverage footprint. The 5G cells have small coverage because 5G networks run at very high frequencies which have very high path loss. In addition to that, the 5G cells are designed to have low heights. Therefore, the likelihood is high of having UE moving back from 5G networks to the lower networks, and vice versa. During that UE needs to make Tracking Area Update. Making Tracking Area Update helps to configure the network to switch the paging messages to a specific network and clear it from the rest 5G network. During the Tracking Area Update, UE cannot make or receive any other sessions. Having more unnecessary Tracking Area Updates yields to have a low quality of service. This paper produces a new Tracking Area Update and paging scenario for inter-networks which are sorted as collocated networks with 5G network.
5G网络是现有4G、3G、2G网络之上的新一层。开发5G网络面临很多挑战。主要的挑战是覆盖范围。5G蜂窝的覆盖范围很小,因为5G网络运行在非常高的频率上,具有非常高的路径损耗。除此之外,5G电池的设计高度也很低。因此,UE从5G网络转回低端网络的可能性很高,反之亦然。在此期间,UE需要进行跟踪区域更新。通过更新跟踪区域,可以配置网络将寻呼消息切换到特定网络,并从其他5G网络中清除。在跟踪区域更新期间,UE不能发起或接收任何其他会话。拥有更多不必要的跟踪区域更新会导致服务质量降低。本文提出了一种新的网络间跟踪区域更新和分页场景,并将其分类为与5G网络并置的网络。

Developing a 5G network has a lot of challenges. The main challenge is the coverage footprint. The 5G cells have small coverage because 5G networks run at very high frequencies which have very high path loss. In addition to that, the 5G cells are designed to have low heights. Therefore, the likelihood is high of having UE moving back from 5G networks to the lower networks, and vice versa. During that UE needs to make Tracking Area Update.

Smart power-strip: Home automation by bringing outlets into the IoT 智能插板:通过将插座引入物联网实现家庭自动化
Yoonill Lee, Jean Jiang, Gabriel Underwood, Austin Sanders, Matt Osborne
In this paper, a device called the Smart Power-Strip is presented. It functions as a wall outlet adapter that is controlled by a microcontroller and can turn any standard home into an automated home without additional construction. It can obtain information by wi-fi connection or sensors then the microcontroller makes a decision based on the obtained information (e.g., programmed parameters). Furthermore, a user can access information and control devices that are plugged into the Smart Power-Strip remotely by using Blynk, which is designed for the Internet of Things (IoT). Therefore, the Smart Power-Strip can bridge the gap between standard homes and the latest in consumer technology.
本文提出了一种称为智能电源插板的器件。它的功能是作为一个由微控制器控制的墙壁插座适配器,可以将任何标准的家庭变成一个自动化的家庭,而无需额外的建设。它可以通过wi-fi连接或传感器获取信息,然后微控制器根据获得的信息(例如,编程参数)做出决策。此外,用户还可以使用专为物联网(IoT)设计的Blynk远程访问插入智能电源插板的信息和控制设备。因此,智能电源板可以弥合标准家庭与最新消费技术之间的差距。
