Invest64 shows investors a total view of their entire portfolio supporting any kind of investment type. 14 Types such as Property, Shares, Funds, Options, Businesses, etc. are already available plus other customisable types.
It handles many languages, unlimited currencies, unlimited securities and profiles. It gives a perfect view of the annual return for an investment, taking into account the actual cash flow. Therefore, gearing, interest only, principal and interest, selling costs, regular repayments will be considered properly.
Transaction types are unlimited, which means even plumber costs for an investment property will be considered. All investments can be linked to securities, such as property, shares, options or even a coin collection or a racehorse. Additionally investment types and transaction types can be defined, which means even very specific tax implications can be customized. The user can define even every single field for each transaction type. For instance plumber costs for an investment property or regular agistment fees for a racehorse will be considered.
An unlimited number of portfolios can be easily defined such as retirement, family or single holder. Investments can be reused among different portfolios. The result data can be displayed in 18 different graphs/lists and favourites can be defined to access them quickly. The graphs show the results by investment institution, account, portfolios or holder. Even these portfolios show the proper annual returns considering actual cash flows.
A modern user interface with multi window, multi view architecture allows easy handling of the application. Help can be directly started from the application. Finally features like three different look and feels, history, loan simulators, security administrators, unit prices for securities and currencies make Invest64 an easily usable and customisable investment tool. The languages English, German and Italian are supported

MedCalc is a stand-alone computer program for statistics in the biomedical sciences. It has an integrated spreadsheet which can be configured to contain up to 520 columns and 32766 rows. The program correctly handles missing data and provides reliable date arithmetic. MedCalc can import Excel, SPSS, DBase and Lotus files, and files in SYLK, DIF or text format.
Comprehensive on line help is available and, in addition to a manual in PDF format, a complete user manual is available on the web.
Special features of the program are, amongst others, lots of graphs including Kaplan-Meier survival plots, Bland & Altman plot, Deming and Passing & Bablok regression for method comparison. MedCalc also includes a complete module for Receiver Operating Characteristic (ROC) curve analysis, with calculation of sensitivity, specificity, likelihood ratios, and positive and negative predictive values for all possible threshold values. The program calculates the area under the curve (AUC) with its standard error and 95% confidence interval. Furthermore, threshold values can be selected in an interactive dot diagram with automatic calculation of corresponding sensitivity and specificity. Comparison of ROC curves includes calculation of the difference between the areas under the curves, with standard error, 95% confidence interval and P-value.

True Score 2 answers practical questions from test scores for managing your course, teaching, and students. It indicates levels of thinking and promotes active learning. A test performance profile graphs the portion of the test that was mastered, unfinished, and discriminating by percent right, question number, and test topic or part. At-risk students are flagged by level of thinking and test topic or part. Multiple version tests are combined into one analysis to save additional time if they are created with True Test Writer. Requires the runtime file msvbvm50.dll. If not in your computer, download from www.simtel.com | VB Runtimes | Msvbvm50.exe. This self-extracting .exe file will install the .dll file.
True Score 2 scores multiple-choice tests both traditionally and alternatively. Students can choose either method or both. It is an easy way for students to change from being passive pupils (lower level of thinking) to being self-correcting, active learners (higher levels of thinking).
Alternative scoring requires students to prepare for the test in the same manner as for an essay test. They must select questions they can answer with confidence rather than work the test for answers and guess. You can use the same questions for both methods of scoring.

NEPM is a very general, highly configurable, two part software system that monitors any type of logged data from IP networked equipment and reports it via E-mail and web pages. Current conditions and history from systems based on Windows NT/2000 and UNIX can be tracked and reported. Most major server, switch and router systems can be monitored, without running agents on the target systems. Many networks behind separate firewalls can be reported on at one central site. NEPM itself is system independent and can be hosted on either a UNIX or WinNT system or a combination of these with equal ease. NEPM monitors and reports uptime, critical events such as intrusion attempts, access rates, bytes-transferred rates, and error rates of network nodes. Unique precursor event links drill down instantly to the causes of downtime, intrusion events, etc. Performance graphs highlight element throughput and error rate. Hardware and software sub-systems within nodes are tracked and reported separately but in a common format that makes possible direct comparison. True hardware uptime is reported so that hardware and software performance can be separated from that of the communications links and from each other. Summary reports and alerts aggregate a view of an entire network's status onto a single page. Reports are provided via web pages posted to a web server for instant access to results. E-mailed text alerts provide prompt notification of dangerous conditions. NEPM is managed via a browser interface, providing full local or remote control from anywhere on the network. Use NEPM to increase your network uptime, increase network security, monitor QOS and SLA's, and evaluate new equipment. Equipment monitored can be Windows or Linux/UNIX/FreeBSD servers, or any processor-based system that logs events to non-volatile storage and has a telnet/rlogin/ssh/IP stream-mode interface.
