This week, University Putra Malaysia's team unveiled their latest inventions and products at the 34th International Exhibition of Inventions, New Techniques and Products in Geneva (April 2-6, 2008), also known as the World's Largest Market-Place for Inventions.
This research is on a software to solve 2nd and 3rd order ordinary differential equations without modifying the structure of the problem tested i.e. not reducing it to the first order system. The code is useful to the scientist, engineers, applied mathematicians and educators to solve many mathematical models in the form of higher order ordinary differential equations in various areas including physics, chemistry, biology, engineering and economics.
TITLE: Direct Block Software for Solving Higher Order Ordinary Differential Equations
RESEARCHERS: Dr. Zanariah Abdul Majid and Prof. Dato’ Dr. Mohamed SuleimanContact details for Dr. Zanariah Abdul Majid
The higher order ODEs can be solved by reducing it to a system of first order ODEs and then solved using any numerical method i.e Euler method. This approach is very well established but it obviously will enlarge the system of first order ODEs. However, the developed code will solve the higher order ODEs directly without reducing it to the first order system. The aim is to solve the higher order ODEs as it appears and never modify the structure of the problem tested.
The code is suitable for solving the numerical integration of non stiff and mildly stiff higher order differential systems. The numerical results obtained are very efficient in terms of accuracy and timing. The source code developed would be useful to the scientist, engineers, applied mathematicians and educators to solve many mathematical models in the form of higher order ordinary differential equations in various areas including physics, chemistry, biology, engineering and economics.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
