Netcat for NT is the tcp/ip "Swiss Army knife" that never made it into any of the resource kits. It has proved to be an extremely versatile tool on the unix platform. So why should NT always be unix s Poor cousin when it comes to tcp/ip testing and exploration? I bet many NT admins out there keep a unix box around to use tools such as Netcat or to test their systems with the unix version of an NT vulnerability exploit. With Netcat for NT part of that feeling disempowerment is over.

Guided vehicles (GVs) are commonly used for the internal transportation of loads in warehouses, production plants and terminals. These guided vehicles can be routed with a variety of vehicle dispatching rules in an attempt to meet performance criteria such as minimizing the average load waiting times. In this research, we use simulation models of three companies to evaluate the performance of several real-time vehicle dispatching rules, in part described in the literature. It appears that there is a clear difference in average load waiting time between the different dispatching rules in the different environments. Simple rules, based on load and vehicle proximity (distance-based) perform best for all cases. The penalty for this is a relatively high maximum load waiting time. A distance-based rule with time truncation, giving more priority to loads that have to wait longer than a time threshold, appears to yield the best possible overall performance. A rule that particularly considers load-waiting time performs Poor overall. We also show that using little pre-arrival information of loads leads to a significant improvement in the performance of the dispatching rules without changing their performance ranking.

In cellular networks, it is estimated that 2 3 of calls and over 90% of data services occur indoors. However, some surveys show that many households and businesses experience a Poor indoor coverage problem. It has been identified that Poor coverage is the main reason for churn, which is very costly for operators in saturated markets. How to provide good indoor coverage cost effectively is thus a demanding challenge for operators.

入室搶劫事件屢見不鮮,針對此現象進行分析不難發現,造成失竊事件的極大原因是人們慵懶和意識差等不良性格造成習慣性不鎖門.本文以STC89C52單片機為基礎,設計了一種基于人體紅外傳感器的自動關門鎖門裝置,來解決此類問題.The incidents of burglary are so common. It is not difficult to find that the main reason for the burglary is the habit of unlocking of doors caused by people's laziness and Poor consciousness. Based on the single chip microcomputer of STC89C52, a device used with infrared sensor of human body is introduced in this paper, which can achieve the effect of automatic closing and locking doors.
