Snow and ice thermodynamics over the Arctic Ocean were simulated applying a one‐dimensional model. A number of numerical experiments in synoptic (10 days early autumn) seasonal (May–September) scales carried out to investigate impact external forcing, snow physics, model resolution: layers both ranged from 3 40. The forcing was based on situ observations 2003 during Chinese National Research Expedition (CHINARE) as well forecasts analyses European Centre for Medium‐Range Weather Forecasts...

Under the Chinese National Antarctic Research Expedition program in 2006, annual thermal mass balance of landfast ice vicinity Zhongshan Station, Prydz Bay, east Antarctica, was investigated. Sea formed from mid‐February onward, and maximum thickness occurred late November. Snow cover remained thin, blowing snow caused frequent redistribution snow. The vertical salinity showed a “question‐mark‐shaped” profile for most growth season, which only turned into an “I‐shaped” after onset melt....

Abstract Interaction of under‐ice physical, chemical, and biological processes with lake ice/snow cover is examined to better understand how changing winter climate may affect ecosystems. We derived dissolved oxygen (DO) dynamics from high‐frequency observations modified a widely used metabolism model by including the effect freezing thawing on DO concentration. Estimates were produced for production respiration in shallow Mongolian Plateau three winters. Diel, synoptic, seasonal variations...

And then, reasoning rules made based on uncertainty statistical distribution contribute design controller. On MATLAB...

Recently, Mobile Operators shift to 5G non-Standalone (NSA) network, through which fast deployment is easily realized, and tend share radio access network (RAN), so as reduce capital well operational expenditure. In this paper, we choose the design of NSA single anchor, using option "LTE eNB MORAN NR gNB with MOCN" for RAN infrastructure sharing. order adapt our current ensure data transmission continuity, interoperation in multi-band networking considered realized by means differentiated...

Summary As a deep neural networks (DNNs) model compression method, learning‐compression (LC) algorithm based on pre‐trained models and matrix decomposition increases training time ignores the structural information of models. In this manuscript, tensor decomposition‐based direct LC (TDLC) without is proposed. TDLC, eliminated, first applied to preserve features model. There are two key steps in TDLC. An optimal rank selection method proposed compression‐step (C‐step) TDLC find global ranks...

Flame photometion analysis technics possess many advantages. In past several decades, flame photometric have draw much attention to the inspectoion workers, and has obtained considerable development, particularly on its fusion technique. The main elements of toxicants are materials which contain P, S, Cl, a great meaning for detect them. textual research expresses. multi-sensor technology can achieve harmful materials, especially those contains Cl.

Intrusion detection is an essential component of critical infrastructure protection mechanism. Since many current IDSs are constructed by manual encoding expert knowledge, it time-consuming to update their knowledge. In order solve this problem, effective method for misuse intrusion with low cost and high efficiency presented. This paper gives overview our research in building a model identifying known intrusions, variations novel attacks unknown natures. The based on rough set theory...

In order to effectively increase the control quality of load frequency controller, this paper proposes a Cloud-Neural Network PI controller based on cloud theory solve adverse effects uncertainties in interconnected power system. Cloud solves uncertain problems by skillfully combining probability statistics with fuzzy theory, but relies heavily artificial experience, while proposed neural network algorithm can learn rules itself. Therefore, cloud-neural problem fixing membership functions...

The cross-talk and coupling effect between SiC MOSFETs in the phase-leg configuration limits further release of MOSFET performance applications. A significant negative voltage spike on gate-source will breakdown device, even deteriorate peculiarities threshold variation impact lifetime. In consideration common source inductance, still needs mechanism research. This paper reveals dynamic underdamped to explain inductance configuration. Experimental results verify this based experimental...

One main technical means of anti-Spam is to build filters in email transfer route. However, the design many junk mail hasn't made use whole security information an email, which exists mostly header rather than text and accessory. In this paper, data mining based on rough sets introduced a new filter. Firstly, by recording analyzing every collected sample, we get all necessary original raw data. Next, selecting computing features from data, obtain our decision table including several...
