ChemDigiT

ChemDigiT is a chemical calculator. No approximations made. All calculated variables show their exact values. The algorithm used for calculations is based on a full set of equations describing acid/base and salt dissociation equlibrium solved with Newton–Raphson method.

Sicyon Calculator

Sicyon is an all-in-one scientific calculator for every student or professor, researcher or developer-everybody doing physics or chemistry/science or engineering using formulas and tables of constants. It is easy-to-use and has everything you need to calculate or investigate a function - chart, roots, min/max, integral, derivative, fit data over, etc. Sicyon calculator combines an intuitive interface and an object oriented approach to provide a fast learning curve while staying at a high level of efficiency. Sicyon calculator is a freeware (under the Creative Commons by-nv-nd-3.0 licence).

BoneLab

BoneLab is a teaching and learning tool for medical professionals, students and anyone who is interested in skeletal anatomy. It is based on the integrated human 3D skeleton model with the highest level of detail presently available. 

Students can interact with the 3D model and create new views, colorize it, add annotations and notes and save it. Instructors can use BoneLab to teach and present anatomical content to students and patients, using predefined views. A dictionary of annotation words is automatically maintained and helps to quickly access all views related to a specific anatomical term. By adding views and annotations, the personalized dictionary will grow and will adapt to individual anatomical content, language and learning habits. 

Mendeley

COCOMO II

COnstructive COst MOdel II (COCOMO II) is a model that allows one to estimate the cost, effort, and schedule when planning a new software development activity. COCOMO® II is the latest major extension to the original COCOMO (COCOMO 81) model published in 1981. It consists of three submodels, each one offering increased fidelity the further along one is in the project planning and design process. Listed in increasing fidelity, these submodels are called the Applications Composition, Early Design, and Post-architecture models.
