In the past, WFM was handled using spreadsheets and time recording, which are time-consuming, lead to non-productive idle times and poor customer service, and incur high operational costs. Currently businesses are using WFM software, which helps manage workforce scheduling, increase operational performance, and identify and solve workforce-related issues in less time. WFM solutions can be deployed across organizations and are beneficial to all types of businesses, as they ensure optimal utilization of resources.

IT is an integrated platform which includes hardware, software, and services. The IT department of a company is responsible for storing, protecting, processing, transmitting, and retrieving information. It helps to develop a secure cyber environment, maintain a uniform flow of information, and increase the revenue generation of an organization.

Insurance is a financial instrument, it is a contract that involves two parties: the insurer and the insured. Based on the contract policies and conditions, the insured pays a premium to cover the specified asset or life. The life insurance policy is a contract between the insurer and the insured, under which the premiums are received, and the insurer agrees to pay a sum of money based on the conditions in the policy. The insurance market in India is an established one. Digitization of insurance is expected to increase the penetration rate of life insurance policies because of wider availability of technologically advanced products online. Insurance policies are broadly classified as traditional and ULIPs. The improvements in internet infrastructure and the rising cost of insurance policies are major factors that pave the way for online life insurance. With public entities such as LIC entering the online insurance market, the credibility of policies purchased online is strengthened, thereby leading to higher enrollment for online policies. As a result, there has been an increase in activities pertaining to sales as well as renewal of insurance policies via the online medium. Policyholders who purchased policies in a traditional manner are also using the online method for renewals and paying premiums.

Social gaming refers to online games played on social media platforms, networks, or within social media applications. The popularity of social games stems from the collaboration between Facebook and Farmville, a game developed by Zynga in 2009. The US is one of the biggest markets for social games. The presence of a large number of people with accounts on social networking sites and other platforms is fostering the market growth. Most vendors launch advanced games in the US to tap the growing market and generate additional revenue. For instance, games such as Candy Crush Saga and the FIFA series witnessed an increase in their gaming base following their launch on social media platforms in the US.

为提高航空公路图像中不良天气中的清晰度，提出一种基于改进分数阶微分算子及景深尺度变化Retinex的图像增强算法。首先将图像进行一种新的分数阶微分操作，然后将雾图像作暗原色先验处理，得到图像的估计景深图，计算原图各处的Retinex尺度，再进行单尺度Retinex变换得到结果图像。实验结果表明，与现有的He算法及其它算法相比，对于场景深度差异较大的模糊航空图像，本文研究的算法具有更快的运行速度和图像增强效果。

针对视频镜头关键帧特征提取矩阵存在尺寸大小不一致而导致相似度无法计算的问题，提出一种广义相似距核视频关键帧分层聚类算法。首先，针对行数相同列不同的两个特征矩阵，基于矩阵运算方法提出一种广义相似距核相似度计算方法并给出其改进形式。其次，基于改进相似距核计算方法和层次聚类算法，设计了广义相似距核视频关键帧分层聚类算法。最后，通过在测试视频数据库及人造视频片段库上的仿真实验表明，该算法能够有效的完成视频关键帧的聚类和提取操作。

针对H.264视频压缩码流在信道传输过程中易发生丢包和误码错误，以及视频图像解码重建后人脸区域模糊等问题，提出了一种基于自适应方向插值及相似性约束人脸区域的错误隐藏算法，对错误块进行两次错误隐藏。首先利用自适应方向插值空域错误隐藏算法对错误块中每个像素点根据其纹理方向进行自适应方向插值运算并恢复，实现第一次错误隐藏，然后提取错误块视频图像的前景目标，采用肤色分割的方法定位出可能的人脸区域，再基于相似性约束方法确定用于覆盖错误块人脸区域的目标人脸区域，通过仿射变换后，将目标人脸区域的梯度信息覆盖错误块的人脸区域，实现第二次错误隐藏。改进的方法能够更加精确的确定插值方向且更好的恢复人脸区域，重建后的视频平滑性有一定的改善。采用JM8.6平台仿真结果表明，与现有基于人脸五官特征的空域差错掩盖算法相比，视频图像隐藏效果在主观视觉上有一定改善，计算出的峰值信噪比（PSNR）提高了1.21dB。

This dissertation investigates the challenges of designing efficient mm-wave transmitters for both long range and short range applications,and proposes concepts and techniques that can potentially break the barriers imposed by the low cost digital CMOS process. The scope of investigation and proposal extends from the architecture level down to the transistor level. Specifically, on-chip and spatial power combining techniques are analyzed and implemented to achieve larger transmitter Equivalent Isotropically Radiated Power (EIRP). To enhance the average efficiency for modulated signals with high Peak-to-Average-Power-Ratio (PAPR), a direct digital-to-RF conversion architecture is proposed and implemented, enabling dynamic DC power scaling. Finally, a Quadrature Spatial Combining concept is introduced to eliminate the tradeoff between low insertion loss and high isolation present in a traditional Cartesian architecture with on-chip signal combiners. Prototype chips are fabricated and tested in 65nm CMOS technology to verify the proposed architectures and techniques.

Two novel, low-cost tactile sensors were designed for use in palm-size (approx. 10 cm in length, under 50 g in mass) crawling robots. The first is a binary, hair-based sensor array, which uses bio-inspired polymer hairs to detect both normal and shear contact forces. The hair sensors have an average normal sensitivity under 1 gram-force (1 gf approx. 10 mN), making them adequately sensitive for use in small, lightweight robots. Furthermore, the hair sensor array has a unique laminar design that allows it to be rapidly-manufactured using a layered roll-to-roll process. In a sample application, it was shown that the binary hair sensor array can be used to estimate average ground speed and to detect high-centering when running over simple obstacles by tracking the propagation of contact along the base of a crawling robot. The second sensor discussed in this work is an analog tactile bumper array that provides robots with the ability to measure contact forces when bumping into obstacles. The sensor consists of an array of laser-cut foam structures that were mechanically designed to exhibit two force sensitivity ranges. The tactile bumper is also cheap and easy to fabricate, using an array of laser-cut foam structures with analog photointerrupters to measure force.
