The proposed system introduces an industrial surveillance system providing a secure data flow with privacy & authenticity in the domain of Automation. This system makes use of Raspberry Pi to provide automation in a workplace environment, utilizing the benefits of IoT. It is used in an industrial scenario for authenticating and monitoring entry and exit of employees, automatic turning ON/OFF of lights and temperature control. All operations are controlled by Raspberry Pi which also acts as the server. Programming languages used are Python & C. Entry and exit of employees are authenticated using Finger Print Scanner. All the information of an employee along with finger print template is already enrolled in database. So every time, the input from fingerprint sensor is authenticated with templates in database to provide access and store time logs. Similarly inputs from temperature sensor and LDR are accessed and sent to server for uninterrupted monitoring and safety services. MQTT protocol is used as the communication protocol for transferring data to IOT server.

Flow Information

We present λCIL, a typed λ-calculus which serves as the foundation for a typed intermediate language for optimizing compilers for higher-order polymorphic programming languages. The key innovation of λCIL is a novel formulation of intersection and union types and flow labels on both terms and types. These flow types can encode polyvariant control and data flow information within a polymorphically typed program representation. Flow types can guide a compiler in generating customized data representations in a strongly typed setting. Since λCIL enjoys confluence, standardization, and subject reduction properties, it is a valuable tool for reasoning about programs and program transformations.

A Performance

The paper presents a complete approach to the multithreaded execution of a control program prepared according to IEC61131-3 standard. The program is mapped to a dedicated multiple-core CPU unit. The CPU consists of multiple independent bit and word CPUs. The computation synchronization mechanism is based on memory cells with semaphored access, which enable hardware-level synchronization. The paper presents in detail the architecture, results of implementation and the achieved performance. The custom-developed compiler translates standard programming languages into a multithreaded executable form. It utilizes an original intermediate data flow graph to optimize and recognize program parallelisms. The program is automatically partitioned and mapped to the available computing resources. The paper is concluded with a performance comparison of program executions using the standard single-threaded and proposed approaches.

Pifagor Programming Language

The paper considers methods of program transformation equivalent to optimizing the cycle invariant, applied to the functional data-flow model implemented in the Pifagor programming language. Optimization of the cycle invariant in imperative programming languages is reduced to a displacement from the cycle of computations that do not depend on variables that are changes in the loop. A feature of the functional data flow parallel programming language Pifagor is the absence of explicitly specified cyclic computations (the loop operator). However, recurring calculations in this language can be specified recursively or by applying specific language constructs (parallel lists). Both mechanisms provide the possibility of parallel execution. In the case of optimizing a recursive function, repeated calculations are carried out into an auxiliary function, the main function performing only the calculation of the invariant. When optimizing the invariant in computations over parallel lists, the calculation of the invariant moves from the function that executes over the list items to the function containing the call. The paper provides a definition of ”invariant” applied to the Pifagor language, algorithms for its optimization, and examples of program source codes, their graph representations (the program dependence graph) before and after optimization. The algorithm shown for computations over parallel lists is applicable only to the Pifagor language, because it rests upon specific data structures and the computational model of this language. However, the algorithm for transforming recursive functions may be applied to other programming languages.
