OmniShare : Encrypted Cloud Storage for the Multi-Device Era
Two attractive features of cloud storage services are (1) the automatic synchronization of files between multiple devices and (2) the possibility of sharing files with other users. However, many users are concerned about the security and privacy of data stored in the cloud. Client-side encryption is an effective safeguard, but it requires all client devices to have the decryption key. Current solutions derive these keys from user-chosen passwords, which are easily guessed. We present OmniShare, the first scheme to combine strong client-side encryption with intuitive key distribution mechanisms to enable access from multiple client devices and sharing between users. OmniShare uses a novel combination of out-of-band channels (including QR codes and ultrasonic communication), as well as the cloud storage service itself, to authenticate new devices. We describe the design and implementation of OmniShare and explain how we evaluated its security (using formal methods), its performance (benchmarks), and its usability (cognitive walkthrough).Two attractive features of cloud storage services are (1) the automatic synchronization of files between multiple devices and (2) the possibility of sharing files with other users.

DESIGN AND SIMULATION OF HIGH SPEED LOW-POWER DUAL-MODE (NRZ/PAM4 12.8Gbps/25.6Gbps) SERIALIZER AND LASER DRIVER IN TSMC 65nm TECHNOLOGY
This thesis presents the design and simulation of the schematic of a low-power (5.6pJ/b) dual-mode (12.8 Gbps NRZ, 25.6 Gbps PAM4) serializer with driver to be used in high-speed serial link transmitter application-specific integrated circuit (ASIC) to be employed in High-Energy Physics (HEP) experiments.
The serializer and driver are being designed in a 65 nm CMOS technology. The ASIC itself will mainly include an LC-VCO phase-locked-loop (PLL), a 32:2 serializer and a CML driver. The driver also employs FIR pre-emphasis using a 2-bit programmable buffer delay chain. The serializer, driver and pre-emphasis are designed based on a combination of architectures presented in literature.
A VCSEL model based on literature is designed using cadence schematic. Verilog-A module is instantiated to emulate the non-linear optical low-pass filtering response of a VCSEL and electrical components are built to form the electrical part of the VCSEL model.
The schematic of the PAM-4/NRZ transmitter presented in this thesis is shown to have an energy efficiency of 5.6pJ/b (with serializer) and 3.71pJ/b (without serializer). Substantial improvements in vertical eye openings and jitter were recorded due to pre-emphasis.Electrical and Computer Engineering, Department o

Role of intravascular methylprednisolone in surgical impaction: An original research
Introduction: Mandibular impacted third molar surgical extraction may cause pain, trismus and swelling. Hence in this study we aim to evaluate the effect of methylprednisolone injection into the muscles on pain edema and trismus post third molar impaction. Material and Methods: We injected methylprednisolone acetate into the masseter muscle via the intrabuccal approach, one hour before the surgery and immediately after suturing of the surgical wound, among the 100 subjects divided to two groups as case and controls, we evaluated postoperative pain, trismus and swelling. The numeric pain scale (NPS) was used for pain assessment. Results: we observed that superior results in preoperative group for mouth opening, pain and all the facial swelling parameters, they were also statistically significant differences than when the postoperatively administered methylprednisolone acetate. Conclusions: Preoperative administration of the methylprednisolone is more effective in reducing pain, trismus and swelling, when compared to that administered postoperatively
