School Management System
ÀKURA is a School Management System that utilizes the latest technology to facilitate a new managerial experience for the Principal and Teachers of a School and Parents. In an era where technology plays a pivotal role in every area of the society, ÀKURA comes to Schools giving them a better management experience for all functionalities of the School. ÀKURA manages the attendance, the academic activities, the co-curricular activities and assists in the religious activities and discipline of a School. The Principals and Teachers could view the progress of a Student at a personal level and also at a class and grade level which provides a good measure of the Student’s progress within the School. At a time where the Parent – Teacher interaction is difficult to manage with the increasing workload of each individual, ÀKURA creates an easy to use Parent – Teacher interaction mechanism. Parents will now be updated on a regular basis on the progress of their children.
Qt based report solution
CuteReport is a report solution like Jasper Report, Crystal Reports or FastReport, but based on Qt framework. It can be easily used with any Qt application. In general, CuteReport consists of two parts: core library and template designer. Both are totally modular and theirs functionality can be easily extended by writing additional modules. It's totally abstract of used data and can use as storage: file system, database, version control systems, etc. The project's goal is to provide powerful, but yet simple to use for inexperienced user and report designers, reporting system. It is supposed to be a product that combines eXaro ideas from Qt world and FastReport functionality from Delphi world and brings the best of them to C++/Qt world and then shares it with Python, Ruby, Perl developers using bindings. СuteReport also has a commercial version. Read about it on the official web site.

An OpenSource Least-Squares-Adjustment Tool
JAG3D is a simple tool to estimate geodetic 1d, 2d and 3d-networks by a least-squares-adjustment called Gauß-Markov model. For gross-error detection, the software supports common outliers tests (based on hypothesis testing) and robust L1 norm (BIBER estimator). Moreover, the software supports deformation-analysis on the observation level. This network adjustment application supports classic observations: - Distances 2D/3D, - Directions and/or azimuths, - Zenith angles, - Levelling difference as well as - GNSS-baselines 1D, 2D and 3D. Further feature (add-ons): - Coordinate-transformation (CoordTrans), - Form analyser (FormFittingToolbox), - Datum-transformation (UTM, Gauß-Krüger, Soldner; WGS84, Bessel, Krassowski, Hayford; NTv2 ...)
