Nefarious users that manage to compromise insecure smart meters can alter the payload transmitted from these meters, and abruptly increase or reduce electricity demand in a coordinated manner. This malicious practice, known as false data injection attack, can destabilize the grid. This paper describes a practical framework for diagnosing false data injection attacks in the smart grid. We propose a behavioral-based monitoring system that can be installed at home-area networks for detecting the aforementioned anomalies. We demonstrate a real-world prototype of our system engineered with inexpensive devices such as Raspberry Pi's and Z-Wave wireless sensors, and evaluate its performance with real data.

Coating contains unique Nano-sized reactive materials which first penetrate the rust and scale to its morphological depth and then migrate to the non-corroded metal surface. Once the particles penetrate to metal surface, they polymerize and completely encapsulate and arrest the rust by forming a highly crosslinked network that is impervious to moisture and corrosive salts. The coating forms a long-lasting chemical and physical bond with base metal. Results over cleaned pretreated steel surfaces can exceed 10,000-hour salt spray with no blisters or scribe creep when top coated. Many coatings for use in refinery or off shore applications are comprised of three layers, which may include 75 to 150 microns of a zinc rich primer, 25 to 35 microns of an epoxy primer and 60 to 100 microns of a two-component urethane topcoat. The new innovative technology described herein provides a significant benefit in terms of 1) improved performance 2) elimination of the epoxy primer coat and 3) material and labor cost savings as the primer is applied at 100 to 125 microns and the topcoat at 75 to 100 microns.

However, the challenge still remains with the electrostatic application of powder and liquid coatings that enable acceptable adhesion to non-traditional substrates (porous substrates like MDF, particle board, trim board and non-porous substrates like wood plastic composites, plastics composites, glass, ceramic etc.) and achieve good transfer efficiency. Insufficient and/or non-uniform surface treatment of these substrates prior to application results in a non-uniform finish, multiple film defects and poor transfer efficiency.
Our research has led to the development of rapid drying conductive adhesion promoters (CAP’s) with improved adhesion of powder and liquid coatings to nonconductive substrates such as MDF, particle board, trim board, wood plastic composites, fiber reinforced composites, ABS, Polycarbonate, Noryl GTXTM, SMC and Polyolefinics etc.; while at the same time improving transfer efficiency by dissipating static charge. The ability of our CAP technology to dry quickly permits application in a continuous/conveyorized production line followed by the application and curing of powder and liquid coatings. The use of CAP’s in this process eliminates the need for preheating, plasma treatment and chemical etching of plastic substrates while improving both film appearance and application efficiency. UV curable as well as LTC (low temperature cure) powder and liquid coatings can now be applied uniformly even in recess areas/faraday cage areas. This patent pending technology utilizes novel conductive materials in conjunction with a polymeric adhesion promoter and at the same time improves flexibility and interfacial adhesion along with anti-static properties.
Conventional treatments used to enhance surface conductivity utilize quaternary ammonium salts dispersions (QAS) which render the coated substrate conductive, but moisture sensitive as the QAS conductive treatment are water sensitive and migratory. Lastly, QAS technology does not enhance adhesion and flexibility.
