MACs: Multi-Attribute Co-clusters with High Correlation Information [chapter]

Kelvin Sim, Vivekanand Gopalkrishnan, Hon Nian Chua, See-Kiong Ng
2009 Lecture Notes in Computer Science  
The generalized formula enables us to use correlation information to discover multi-attribute co-clusters (MACs).  ...  We develop a novel algorithm MACminer to mine MACs with high correlation information from datasets.  ...  (b) Multi-attribute co-clustering. The pair of clusters with horizontal lines form a multi-attribute co-cluster, and so do the pair of clusters with vertical lines.  ...

2009 Sensors  
Then we study low-power MAC protocols proposed/investigated for WBAN with emphasis on their strengths and weaknesses. We also review different power-efficient mechanisms for WBAN.  ...  In addition, useful suggestions are given to help the MAC designers to develop a low-power MAC protocol that will satisfy the stringent WBAN requirements.  ...  Information Technology Advancement (IITA) (IITA-2009-C1090-0902-0019).  ...

We present high resolution (9^") imaging of the Sunyaev-Zel'dovich Effect (SZE) toward two massive galaxy clusters, MACS J0647.7+7015 (z=0.591) and MACS J1206.2-0847 (z=0.439).  ...  For MACS J0647.7+7015, we find a gNFW profile with core slope parameter γ= 0.9 fits the MUSTANG image with χ^2_red=1.005 and probability to exceed (PTE) = 0.34.  ...  For more information about MUSTANG, refer to Dicker et al.

Low-frequency radio study of MACS clusters at 610 and 235 MHz using the GMRT [article]

Surajit Paul, Sameer Salunkhe, Abhirup Datta, Huib T. Intema
2019 arXiv   pre-print
Our observations have also revealed an ongoing second merger along with a close-by high-speed (1769±^148_359 km s^-1) merger-shock (M=2.02±^17_41), thus providing a possible clue to the halo-relic co-existence  ...  Here we present GMRT dual-band (235 and 610 MHz) radio observations of four such merging cluster candidates from the MAssive Cluster Survey (MACS) catalogue.  ...  This also informs us about a galaxy cluster merger that has taken place at such an early stages (at high redshift) of structure formation in the Universe.  ...

Our Chandra observation of the system yields a total X-ray luminosity of 2.4 x 10^45 erg/s (0.1-2.4 keV) and a global gas temperature of (11.6 +/- 0.7) keV, very high values typical of MACS clusters.  ...  We discuss the X-ray and optical properties of the massive galaxy cluster MACSJ1206.2-0847 (z=0.4385), discovered in the Massive Cluster Survey (MACS).  ...  Final refined redshifts were found with a multi-template cross-correlation method using the iraf task fxcor.  ...

Joint HST, VLT/MUSE and XMM-Newton observations to constrain the mass distribution of the two strong lensing galaxy clusters: MACS J0242.5-2132 MACS J0949.8+1708 [article]

2022 arXiv   pre-print
Combining our analysis with X-ray observations from the XMM-Newton Observatory, we show that MACS J0242 appears to be a relatively relaxed cluster, while conversely, MACS J0949 shows a relaxing post-merger  ...  For each cluster, our best-fit mass model consists of a single cluster-scale halo, and 57 (170) galaxy-scale halos for MACS J0242 (MACS J0949).  ...  DESI Legacy Survey Since the available HST imaging for MACS J0242 are shallow and colour information is limited to a WFPC2-sized footprint, we complement these data with additional multi-band ground-based  ...

We present an analysis of the merging cluster MACS J1149.5+2223 using archival imaging from Subaru/Suprime-Cam and multi-object spectroscopy from Keck/DEIMOS and Gemini/GMOS.  ...  We show the merger to be returning from apocenter with core passage occurring 1.16^+0.50_-0.25 Gyr before the observed state.  ...  The LOS velocity difference is attributed to a peculiar velocity, in which case, subcluster three is merging with subcluster one at a very high velocity along the LOS.  ...

Literature Review of MAC, Routing and Cross Layer Design Protocols for WSN [chapter]

Tayseer AL-Khdour, Uthman Baroudi
2011 Wireless Sensor Networks  
The MAC protocol must be able to support a large number of nodes. It must have a high degree of scalability. The MAC protocol must take into account the limited bandwidth availability.  ...  WSN is considered a multi-hop network.  ...  Therefore, each node must have information about child attribute values. Unequal Cluster Based routing (UCR): In UCR protocol, clusters with different size are constructed (Guihai  ...

Gold-mineralized zones exhibit a strong geochemical correlation with As-Ag-Te-Pb-Bi /-Cu-Co -a unique suite of pathfinder elements in the district.  ...  In this way we hope to learn from geological corrosion behaviour to inform and improve DGR multi-barrier design.  ...  We note that chains of correlation, because of their precise chronology, could be linked with other disciplinary-based time scales, none having more importance than the others, but when correlated together  ...

This is a virialized population found at higher cluster-centric radii with sizes similar to the quiescent, spheroid-dominated population of the cluster center, but with disks still in-tact.  ...  We attribute this to longer quenching timescales of more massive galaxies in the cluster. Our analysis further revealed an increasing importance of recently quenched transition objects ("red disks").  ...  The CLASH Multi-Cycle Treasury Program is based on observations made with the NASA/ESA Hubble Space Telescope.  ...
