Also referred to as Axes, the maximum reach of material deposition end effector determines the maximum size of the part that can be built. Inherent to most the SFF system is the drive configuration that limits the extent of the reach of the end effector. This paper proposes an alternate architecture that overcomes the drive limitations and hence provides an ability to enhance the work envelope. Two systems proposed include – (1) Cartesian axis stacking and (2) Common Vehicle arrangement. The system drive may be built such that multiple units can be combined and reconFigure d to expand the total work envelope. Introduction Shape and size of the parts manufactured by Most of the Solid Freeform systems also referred to as the 3D printing equipment is limited by work envelope of the System. Despite being a general purpose manufacturing system most of the 3D printers...

Traditional IEEE802.11 works in Distributed Coordination Function (DCF) mode and uses Binary Exponential Backoff (BEB) algorithm. The proposed new backoff algorithm works on the exponential decrease of contention window. In the algorithm, the size of contention window does not decrease down to zero on a successful transmission rather decreases exponentially. This improves performance for high contention scenarios in CRN. The reported work also focuses on primary user receiver (PU receiver) protection from the hazardous transmission encountered due to presence of nearby CR traffic. The novelty of protection algorithm lies in the approach of accessing location and other relevant inform from PU. Here a CR node can access location of PU with the help of GPS system. Further the primary receiver protection is done by implementing a power control algorithm at CR user end. The performance of the ...

The work presents a comparison of the analysis in the two frames and comments on mathematical and physical concepts involved in solving the problem. The results are then represented in terms of simulations and solutions are thoroughly discussed, in an effort to give students, a clear picture of the importance of the two frames. The article is aimed at the undergraduate level students.

[1,2] The UK government has identified the key outcomes, which matter most to children, including child being healthy and staying safe (i.e., being protected from harm and neglect). [3] Currently, the definition given by CAPTA (Child Abuse Prevention and Treatment Act) also includes sexual abuse, sexual exploitation, physical or emotional abuse, and willful cruelty or unjustifiable punishment of a child. [4] Child trafficking is also considered as a form of child abuse, which largely remains hidden within our society. Last decade has brought a growing awareness of this form of abuse which has significant and far-reaching consequences among children. [5] Background: Anganwadi workers (AWW) and auxiliary nurse midwives (ANM) whom we can say in Indian scenario work at grassroot level and ground level, respectively, very close to rural community where child abuse is more frequent and unreported, which affects a child physically, mentally, emotionally, and psychologically. Objective: To assess the level of knowledge, attitude, and practice (KAP) against child abuse among AWW and ANM. Materials and Methods: This study was undertaken with the help of a pretested self-administered questionnaire in both the groups. A total of 69 AWW and 53 ANM during their scheduled monthly meetings were targeted in the study. After explaining the need for the study and assuring confidentiality for answers for the study, they were asked to fill the questionnaire. Completed questionnaires were collected back and subjected to data analysis. Results: The highest mean knowledge score was among AWW and ANM who had 8-10 years of experience, which was statistically significant; the mean attitude score was not statistically significant among AWW and ANM; and the mean practice score was highest among AWW and ANM who had 8-10 years of experience, which was statistically significant. It was found that knowledge correlated significantly with attitude and practice. Conclusion: Knowledge and attitude toward child abuse at grassroot level among AWW is insufficient when compared to ground level among ANM, but practice about procedures and reporting after detection of child abuse was disappointingly lacking among AWW and ANM, urging to enforce and reinforce formal education among them with the help of lectures and printed materials with color plates of abuses, which would enable detection and reporting of this social public health evil to get eradicated.
