This paper presents an integrated approach towards implementation of a multilayered architecture based upon stacked silicon for image capture and secure data transmission suitable for bio-medical devices and implementation within patient-point-of-care network. The system architecture is comprised of a CMOS based image sensor layer, memory layer, 3D-DWT (Three-dimensional Discrete Wavelet Transf...

Today’s need for more complex, more capable systems in a short timeframe is leading more organizations towards the integration of existing systems into networkcentric, knowledge-based system-of-systems (SoS). Software and system cost model tools to-date have focused on the software and system development activities of a single software system. As we view the new SoS architectures, we find that ...

Our main result is a formulation and proof of the reverse hypercontractive inequality in the sumof-squares (SOS) proof system. As a consequence we show that for any constant 0 < γ ≤ 1/4, the SOS/Lasserre SDP hierarchy at degree 4d 1 4γ e certifies the statement “the maximum independent set in the Frankl–Rödl graph FRγ has fractional size o(1)”. Here FR n γ = (V,E) is the graph with V = {0, 1} a...

Many organizations are attempting to provide new system capabilities through the net-centric integration of existing systems into systems of systems (SoS). The engineering activities used to architect and develop these SoS are often referred to as SoS Engineering (SoSE). Recent reports are indicating that SoSE activities are considerably different from classical systems engineering (SE) activit...

Under DoD sponsorship, the Software Engineering Institute has initiated a research project on system of systems (SoS) software assurance. The project’s overall goal is to provide appropriate methods and tools to meet the assurance challenges of systems of systems. To focus the research, the project is specifically addressing SoS assurance issues that arise in large-scale adaptive information ma...

Analysis of interspecies matings between S. typhimurium and E. coli indicates that the genetic barrier that separates these (and perhaps many other) related species is primarily recombinational. The structural component of this barrier is genomic sequence divergence. The mismatch repair enzymes act as potent inhibitors of interspecies recombination, whereas the SOS system acts as an inducible p...

This paper explores verification of constituent systems within the context of the Symphony tool platform for Systems of Systems (SoS). Our SoS modelling language, CML, supports various contractual specification elements, such as state invariants and operation preconditions, which can be used to specify contractual obligations on the constituent systems of a SoS. To support verification of these...

The term Systems of Systems (SoS) has recently been introduced in the systems engineering domain to describe a new class of systems, exhibiting a number of attributes such as complexity, autonomy, and geographic dispersion. The (UK) Ministry of Defence Architectural Framework (MODAF) is a prominent framework used in the defence domain. MODAF is organised in views, each of which focuses on a sin...

Cell division must be tightly coordinated with DNA replication so that a complete genome ends up in each daughter cell. That coordination is especially critical when DNA is damaged, as lengthy delays may be required to repair broken strands. To prevent premature division, cells detect the presence of broken DNA with dedicated sensor proteins, which inhibit division while they promote repair. In...

The vision of the Internet of Things (IoT) based on Smart Objects (SOs) promotes an high-level architectural organization of the future IoT designed around the basic concept of SO. An SO is an autonomous, cyberphysical object augmented with sensing/actuation, processing, storing, and networking capabilities. An important issue in supporting future SO-based IoT systems is how to classify SOs. Cl...
