EMAT: An Engineering Methodology Application Tool

Nanxin Wang, Jie Cheng


More and more applications in today’s automotive industry call for integration of existing product design/analysis programs into packages to perform a higher level of system functionality, such as total engine analysis, model-based engine mapping, and powertrain system or vehicle optimization. The functional and procedural specifications for these integrations are often referred to as engineering methodologies. To enable the rapid prototyping of these methodologies, a generic software integration framework, EMAT (Engineering Methodology Application Tool) has been developed. EMAT consists of a high-level language environment MDL (Methodology Description Language) and a program for process execution scheduling and monitoring based on an artificial intelligence technology called Blackboard. Under the EMAT framework, a user can easily specify the control flow and data flow for any methodology in a declarative manner. Such a specification only needs to contain logical orders in which individual component programs will be executed (such as sequence, branching, or looping), and the input/output connections between the programs. EMAT will then dynamically interpret this specification into procedures that actually carry out the executio...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
