Successfully Hiring and Retaining it Personnel

Despite the current shortage of qualified IT professionals, a midwestern consulting agency more than tripled its number of employees. the hiring practices of the agency are credited for their ability to attract and retain talent. These practices successfully manage technology, candidates' qualifications, competitive pay, openness about the culture of the firm, and candidates' expectations.     

Improving target detection by coupling it with tracking

Target detection and tracking represent two fundamental steps in automatic video-based surveillance systems where the goal is to provide intelligent recognition capabilities by analyzing target behavior. This paper presents a framework for video-based surveillance where target detection is integrated with tracking to improve detection results. In contrast to methods that apply target detection and tracking sequentially and independently from each other, we feed the results of tracking back to the detection stage in order to adaptively optimize the detection threshold and improve system robustness. First, the initial target locations are extracted using background subtraction. To model the background, we employ Support Vector Regression (SVR) which is updated over time using an on-line learning scheme. Target detection is performed by thresholding the outputs of the SVR model. Tracking uses shape projection histograms to iteratively localize the targets and improve the confidence level of detection. For verification, additional information based on size, color and motion information is utilized. Feeding back the results of tracking to the detection stage restricts the range of detection threshold values, suppresses false alarms due to noise, and allows to continuously detect small targets as well as targets undergoing perspective projection distortions. We have validated the proposed framework in two different application scenarios, one detecting vehicles at a traffic intersection using visible video and the other detecting pedestrians at a university campus walkway using thermal video. Our experimental results and comparisons with frame-based detection and kernel-based tracking methods illustrate the robustness of our approach.

CAN协议的错帧漏检率改进

过去对CAN的漏检错帧概率的研究很有限,数据的获得主要依靠大量的仿真测试.由于要仿真的量太大,实际上仿真的仍然是极小的样本,所以得到的漏检错帧概率可信性不足.本文介绍了漏检实例的构造方法,从而进行漏检错帧概率下限的分析计算.得到的CAN协议的漏检错帧概率远大于以前的结论,因此对CAN的应用有巨大的冲击.由于已有大量应用...     

提升资源利用率的MapReduce框架探讨

本文探讨了MapReduce框架,它为控制成本、优化集群资源利用提供了保证。对于分布式计算层面,资源优化有两个途径：一是通过精细化的资源调度来保证全局资源的最大化利用;二是提升原有计算作业的资源使用率。HCE计算框架主要关注后者。     

提高BP网络收敛速率的又一种算法

提高BP网络的训练速率是改善BP网络性能的一项重要任务。该文在误差反向传播算法(BP算法)的基础上提出了一种新的训练算法,该算法对BP网络的传统动量法进行了修改,采用动态权值调整以减少训练时间。文章提供了改进算法的仿真实例,仿真结果表明用该方法解决某些问题时,其相对于BP网络传统算法的优越性。     

Improving Information Quality Through it Alignment Planning: A Case Study

This article describes how a medium-sized, Midwestern power company implemented an IT alignment planning process. the IT alignment planning process was a successful four-year activity that involved, first, a pilot implementation and then a companywide implementation of the IT alignment planning process. Designed to be flexible and to dovetail with corporate strategic planning processes, IT alignment planning achieved acknowledgment and approval in all divisions of the company. the IT alignment planning process improved and facilitated communication on IT and IT projects throughout the company, from the executive level to the operational level, and brought the IT and client units closer together.     

An MIS Manager's Guide to Hiring Programmers

H.264码率控制及其改进策略

H．264／MPEG-4AVC（H．264）是1995年自MPEG-2视频压缩标准发布以后的最新、最有前途的视频压缩标准。在对现有的码率控制算法研究的基础上,提出了一些改进策略,包括对初始量化参数的选取,对跳帧的处理和对场景切换的检测。该方法可使码率控制算法具有更高的效率,在低码率的情况下可以提供更好的图像质量,降低了传输延迟。     

一种提高嵌入式系统UBI分区挂载速度的设计方案与研究

根据Linux嵌入式系统UBI分区的挂载原理,在系统关机时预先扫描UBI设备中PEB块的相关头信息,并进行相关压缩处理后存储在UBI分区中的指定物理位置,使得系统下次开机时内核可直接读取预先存储的扫描信息,节省了大量时间.以关机时间换取开机速度的提高,在大量使用UBIFS的基于NAND flash嵌入式系统应用中有很好的优势.

Variables in the Hiring Equation: Ensuring that the Right Candidate is Hired

When making the decision to hire one of several equally qualified candidates, IS managers fall back on their instincts and choose the candidate that “feels right.” They rely on personal chemistry, which is one of the variables in the hiring equation. Other equally important elements are: aptitude, attitude, and motivational factors.     

Hiring, Firing and Infighting: A Tale of Two Companies

We extend the hiring and firing framework of Shepp and Shiryaev (J Econ Dyn Control 20:1523?C1539, 1996) to include infighting, and solve the profit-maximization problem using our numerical technique. With infighting, we find a smaller optimal firm size, and lowered firm value that stems from reduced operations and rapid profit-taking. Upon calibrating our model to match the cases of Levi Strauss & Co. and Microsoft, we find with Levi??s, that our model matches media estimates of its loss in value fairly closely. With Microsoft, our model might explain its loss in value and poor decision-making, such as its recent acquisitions. The implications of our model for corporate governance might also help in reducing the current unemployment rate.     

Hiring Qualified College Graduates: MIS Business Majors Versus Computer Science Majors

When decisions must be made regarding systems productivity and control trade-offs, many companies automatically opt for productivity improvement. However, critical functions, documentation, testing, and training are sometimes sacrificed. To establish a balance between these competing needs, MIS management should educate systems developers and users about the nature of and need for controls.
