This paper addresses the scheduling of machines, an Automated Guided Vehicle (AGV) and two robots in a Flexible Manufacturing System (FMS) formed in three loop layouts, with objectives to minimize the makespan, mean flow time and mean tardiness. The scheduling optimization is carried out using Sheep Flock Heredity Algorithm (SFHA) and Artificial Immune System (AIS) algorithm. AGV is used for carrying jobs between the Load/Unload station and the machines. The robots are used for loading and unloading the jobs in the machines, and also used for transferring jobs between the machines. The algorithms are applied for test problems taken from the literature and the results obtained using the two algorithms are compared. The results indicate that SFHA performs better than AIS for this problem.

Hospital patient record that is stored in public cloud demands high level of security and access control. To guarantee the proper user access, an authentication scheme is required that can follow up data access. In this paper, counter based authentication verification is introduced. This method utilizes token generation and counter strategy. Elliptic curve based digital signature is employed in token generation. Along with the generated token, the data is encrypted and a counter value is appended to it. Whenever an authorized user views or modifies the stored data, the counter value is updated. Thus, this method significantly identifies an unauthorized data access.

Polyglandular polyendocrine syndromes (PSs) are an assorted collection of infrequent ailments considered by autoimmune motion contrary to more than one endocrine organ, though non-endocrine organs can be affected. The deficiency of parathyroid is quite rare without surgery. This article summarises clinical, epidemiological, and serological, data of patients with PSs. Multifaceted diagnostic difficulties and treatment choices required that the patient be admitted to the hospital for a rather long period, namely for six weeks. Three diabetic patients with various thyroid disorders such as lymphocytic thyroiditis involving parathyroid glands manifesting with severe hypothyroid and hypo-parathyroid status were studied with an occurrence of dengue viral aetiology as a precipitating factor. Further, the patients were investigated for the determination of antibodies against thyroglobulin and microsomal antigens by chemiluminescent microparticle immunoassay. They were also tested for Parathyroid Hormone and 25-hydroxy vitamin D. After three months, all the three hormonal status were brought to normal with substitution and maintenance therapy, and patients were reviewed after six months were found to maintain with the dose. To conclude, thyroiditis may progress during the progression of dengue fever and should be counted as a manifestation of expanded dengue syndrome.
