Device Controller Design Based on the Internet of Things

With of the increasing application of high tech and information technology, wireless sensor network has already become one of the hottest topics. The SmartNet is to build an intelligent home network system. In SmartNet, the format of control string, the interpretation structure of driver, and the network manager protocol were designed. And the design can be divided into two parts: software and hardware. The hardware is mainly defines rules, while the software part is mainly interpret the driver of hardware, generate user interface of the device, and organize and send commands.

Cis-regulatory elements of the mitotic regulator, string/Cdc25

Mitosis in most Drosophila cells is triggered by brief bursts of transcription of string (stg), a Cdc25-type phosphatase that activates the mitotic kinase, Cdk1 (Cdc2). To understand how string transcription is regulated, we analyzed the expression of string-lacZ reporter genes covering approximately 40 kb of the string locus. We also tested protein coding fragments of the string locus of 6 kb to 31.6 kb for their ability to complement loss of string function in embryos and imaginal discs. A plethora of cis-acting elements spread over >30 kb control string transcription in different cells and tissue types. Regulatory elements specific to subsets of epidermal cells, mesoderm, trachea and nurse cells were identified, but the majority of the string locus appears to be devoted to controlling cell proliferation during neurogenesis. Consistent with this, compact promotor-proximal sequences are sufficient for string function during imaginal disc growth, but additional distal elements are required for the development of neural structures in the eye, wing, leg and notum. We suggest that, during evolution, cell-type-specific control elements were acquired by a simple growth-regulated promoter as a means of coordinating cell division with developmental processes, particularly neurogenesis.

Functional unparsing

A string-formatting function such as printf in C seemingly requires dependent types, because its control string determines the rest of its arguments. Examples:formula hereWe show how changing the representation of the control string makes it possible to program printf in ML (which does not allow dependent types). The result is well typed and perceptibly more efficient than the corresponding library functions in Standard ML of New Jersey and in Caml.
