Imagemap applet with menu hotspots. The distinctive feature is the ability to handle non-rectangular (i.e. both polygonal and discontinuous) hotspots in a user-friendly manner. This makes it ideal for geographical maps, building diagrams and machinery documentation where strangely shaped areas need hyperlinks attached..

  • Platform: Java, Scripts

Sensomaps are imagemaps which can handle both polygonal and discontinuous shapes, making them very useful for geographical maps and complex technical diagrams. Preloaded highlight images allow fast emphasis of hotspots. Context-sensitive textual information can be defined by the user to appear in a display panel at the side of the map. Multi-level framecrossing popup menus drop-down or pop-up from hotspots. Highly scalable. Use any GIF or JPG images of your choice..

See paper "Minimum settling time control design through direct search methods" (preprint on http://arxiv.org/abs/1109.5966) by the same author. The settling time of a closed-loop response, depending on controller parameters, is an objective function not only non-smooth but actually discontinuous. Since gradient informations are not available (everywhere), we propose to solve this problem with derivative-free optimization methods (amongst which the direct search methods, not building a model of the objective function, will already prove efficient). Shorter settling times will be obtained on the four examples tried, compared to two state-of-the-art time response shaping techniques.

Do you need a menu based on a map of your home town? Do you need to navigate through a business which is geographically spread around the state or country? Are you compiling technical/scientific documentation where you need pop-up information for strangely shaped parts? Are you preparing and distributing plans of your building to emergency services? All of these situations require sensomap navigation. Main features: Imagemap applet which can manage complex polygonal and discontinuous image-switching hotspots. Ideal for real-world diagrams where the user locates important places visually and then rapidly extracts the information required with a context-sensitive display or pop-up.

Fachwerk is aimed at structural engineers who analyse and design reinforced concrete structures. It intends to simplify the application of discontinuous stress fields and strut-and-tie models. The program calculates strut-and-tie models. It only uses equilibrium conditions. Thus, unlike common programs, it does not assume elastic material behaviour. If the modelled system is statically indeterminate, Fachwerk will nevertheless calculate the forces of the members that are determinate. One can assign forces to the remaining members. If more forces than needed to accomplish a statically determinate system are assigned to members, and the equilibrium condition is not fulfilled, Fachwerk will indicate that the system is inconsistent.

The aim of this simple benchmark is to illustrate the interest of restarting Nelder-Mead locally, from the last solution found, until no improvement is reached (to a given accuracy). Also, it shows that fminsearch has great difficulties at minimizing the most simple, smooth quadractic, objective function used. But restarting it locally corrects that. On the other hand, Nick Higham implementation of Nelder-Mead works fine, and the accuracy reached is also further improved by restarting it locally. Note that it may still happen that fminsearch performs better than nmsmax on other problems. Anyhow in theory, amongst direct search methods, one should not use even the restarted NM but rather MADS (see http://www.

Process modelling and simulation can be defined as theoretical concepts and computational methods that describe, represent in a mathematical form and simulate the functioning of real-world processes.

DAE Tools is a reliable solution designed for modeling and simulating processes in chemical process industry (mass, heat and momentum transfers, chemical reactions, separation processes, thermodynamics). However, DAE Tools can help you develop high-accuracy models of (in general) many different kind of processes/phenomena, simulate/optimize them, visualize and analyse the results.

Its features should be sufficient to enable mathematical description of chemical, physical or socio/economic phenomena.

Toolwiz Smart Defrag is faster by ten times than native defrag of Windows. It can analyse the discontinuous files in the disk within several seconds(the reason for it being faster is it makes use of the undocumented NTFS parsing algorithm by Microsoft and analyses directly without using the file system). Then it quickly puts these discontinuous files in the continuous space in the disk.

Toolwiz Smart Defrag is very simple, and completely free, after installing, you can even extract exe to be used as the Green version.
