An Interactive Approach for Synthesizing UML Statechart Diagrams from Sequence Diagrams

Minimally Adequate Synthesizer (MAS) is an interactive algorithm that synthesizes UML statechart diagrams from sequence diagrams. It follows Angluin’s framework of minimally adequate teacher to infer the desired statechart diagram by consulting the user. To minimize the consultations needed, MAS keeps track of the interaction with the user. Together with its general knowledge about sequence dia...

Low phase noise, high bandwidth frequency synthesis techniques

A quantization noise reduction technique is proposed that allows fractional-N frequency synthesizers to achieve high closed loop bandwidth and low output phase noise simultaneously. Quantization induced phase noise is the bottleneck in state-ofthe-art synthesizer design, and results in a noise-bandwidth tradeoff that typically limits closed loop synthesizer bandwidths to be <100kHz for adequate...

Implementing Modulation Functions in Microwave Frequency Synthesizers

The main function of a frequency synthesizer is to deliver a stable and clean signal. However, many applications require not only a fixed frequency signal but also various modulation functions ranging from simple pulse, amplitude, frequency and phase modulation to complex digital modulation formats. Although modulators are usually realized as external devices, they can also be incorporated into...

Prime Incision and Modified Moving Window: A Minimally Invasive Access for Breast Cancer Surgical Treatment

BACKGROUND Conservative surgical treatment has been the treatment of choice for early breast cancer.&nbsp;It allows feasible oncological treatment with a satisfactory cosmetic approach and fast recovery. However, in some cases mastectomy is necessary. This study proposes a surgical approach with only one surgical access through the same incision, which is in line with precepts mentioned abov...
